TUNE INTO ZERO’s
SOUND SOLUTIONS
ZERO is a world-wide leader in high-performance acoustical control for doors,
windows, walls or floors. Nobody does sound control better — we use
advanced technology and testing to master the challenges of creating an
effective barrier and preventing gaps in that barrier for the life of the assembly.
Our systems are rated for use in sound studios and recording facilities, music
halls, or where ever sound solutions are needed — up to 55 STC. Let us help you
close the door on noise — contact us for a copy of our 20 page Sound Control
brochure, and our 92 page Product Catalog, or download from our website.

of doors pose additional challenges for sound control because there are more
openings to seal. The need for a meeting stile means there will always be relatively
more sound leakage through pair assemblies than with single doors. Properly fitted
STC 52 or higher acoustical doors, ZERO's SOUND TRAP-PAIRS system for
metal doors achieves an office-friendly STC rating of 41 with an optimal configuration
#770
that balances those limitations with appropriate, cost-effective technology.

President’s Column
INCE/USA Announces Collaboration
with the Drohan Management Group
I am very happy to inform you that as of
November 1, 2014 the Drohan Management Group
will have taken over the responsibility for running
the INCE/USA Business Office (IBO). The IBO is
often the main point of contact between the Institute
and its members and handles most of our day-to-day
operations. If you phone INCE/USA, the call will be
answered by the IBO.
The IBO is also called on to provide professional
guidance to the INCE/USA volunteers. Though the
INCE/USA leadership is obviously very familiar
with technical engineering issues, we sometimes
need advice from people who are experts in the
mechanics of running a nonprofit organization. We
may seek advice on topics ranging from database
management to tax and legal issues.
The Drohan Management Group was chosen after
a six-month search. This search began with the
drafting of a scope of services. This scope is an
important document because it defines our needs and
how we wish to run the Institute. There was quite a
bit of discussion and soul searching that went into
developing this document. That scope was included
with a request for proposal and was circulated among
association management companies. We received
over 30 proposals in response to our request. After
careful review of all the proposals, many conference
calls, and an in-person interview, the INCE/USA
search committee unanimously selected the Drohan
Management Group (DMG) and recommended them
to the Board of Directors. The Board of Directors
voted to extend a contract to DMG at our recent
meeting at NOISE-CON 2014 in Fort Lauderdale.
The Drohan Management Group is principally
located in Reston, Virginia, and has been serving
nonprofit organizations for 28 years. They are a
2014 September www.inceusa.org
large organization with over 50 people serving
20 clients. They have extensive expertise in
many areas including finance, communications,
information management, meetings and exhibits,
creative services, and, of course, general association
management functions. Cathy Vail is director of
operations at DGM, and she will be our main contact.
We are very excited to have DMG on board and look
forward to their helping us become more efficient at
serving the INCE/USA membership. Though much
of their work will occur behind the scenes, their
activities will be felt by our membership on many
levels. They will be updating our website, improving
our online member database, improving our
membership response, and helping us identify those
areas where we can better serve the membership.
We will also rely on them to assist with the many
practical aspects of running our conferences—from
negotiating with hotels and AV companies to printing
the program to running the registration booth.
Gordon Ebbitt
President INCE/USA
[email protected]
Though Drohan Management Group will be
handling our operations, Joe Cuschieri will continue
as our executive director. This arrangement will
allow INCE/USA to have a more direct influence
on how our daily operations are handled, and it will
ensure that the best interests of our members are
understood and served. With the assistance of DMG,
however, Joe can begin to shift his attention from
day-to-day issues to longer range strategic planning.
Please join me in welcoming Cathy Vail and the
entire team from the Drohan Management Group
to INCE/USA. I am looking forward to a long and
productive relationship.
As always, if you have any questions or comments,

Editor’s View
Future Member Benefits of I-INCE and INCE-USA
Jim Thompson,
Ph D, PE, INCE Bd.
Cert.
[email protected]
noisenewsinternational.net
What value do INCE-USA and I-INCE provide to
our members, and how will this evolve? I have been
thinking about this recently and feel it is a good topic
for us all to consider. Some organizations are doing
virtual conferences, and there will be more technical
innovations coming in the future. With this article,
I want to introduce some of these topics and ask
for your thoughts and comments. Please note that
none of the questions raised here represent plans
for I-INCE or INCE-USA. They are simply some
questions that need to be considered and which have
already impacted other organizations.
The current value proposition for our institution is
fairly clear. Most members would cite the following
primary benefits:
• Conferences
• Noise/News International
It is also possible to envision doing short, virtual
mini-conferences on specialized topics. Several
years ago there were specialty conferences on sound
quality, materials, and active noise control that were
quite successful. Could these be done electronically?
Would there be value in doing so?
What should the cost be for attending virtually?
Should the virtual attendee pay more or less for the
conference?
Should NCEJ be free to anyone who goes to the
website, like NNI? Would this diminish the value of
membership? If we had to add advertising to defray
the cost of offering NCEJ this way, what would you
think? How would this affect the perceived value
of INCE-USA or I-INCE membership? Would this
make it more or less desirable for you to publish
in NCEJ?
• Noise Control Engineering Journal
• Digital Library
• Certification
• Training courses offered to prepare one for full
membership or certification
These benefits seem to represent real value, and most
members seem to agree.
So, where do we go in the future? People have talked
about virtual conferences. Would there be a loss in
value if you attended a conference over the Internet?
You could see the delivery of papers and perhaps
participate in discussions. However, there would
be some loss in networking and the unexpected
opportunities to learn from interactions in the exhibits
or in the hallways of the conference center. It seems
like many would still prefer to attend the conference
in person. However, for some the cost or other issues
may prevent being there in person. For such cases, a
virtual capability might be a good alternative. Does
this lessen the value for those who do attend? Does it
increase the value for those can be there physically?
I would be interested in your thoughts on this topic.
2014 September www.inceusa.org
What about certification? Does it still provide
value when it is easy to go online and review
someone’s background and education on LinkedIn
or somewhere similar? Should INCE-USA open up
certification to non-INCE members? What should we
charge for such an opportunity? Would $1,000 be
too much?
Should we make the Digital Library open to anyone
at no charge? Would you see this as devaluing
membership? It certainly would be good to have
these 20,000 papers available to anyone interested in
noise control. Would this lead to increased usage of
this resource?
Hopefully you will want to provide feedback.
I will promise to share this feedback with I-INCE
and INCE-USA officers and board members.
These are issues that we need to consider;
other professional organizations have already
taken some steps along these lines. I appreciate
your consideration and look forward to
your response. NNI

Member Society Profile
Welcome to the Swedish Acoustical Society!
Svenska Akustiska Sallskapet or the
Swedish Acoustical Society (SAS)
was established as the focal point of
interest in the field of acoustics within
Sweden. According to its statutes, the
Swedish Acoustical Society, through the
organization of lectures, discussions,
and other activities, encourages the
development of acoustics. The SAS
publishes a journal three times a year,
which contains acoustic news and articles.
Over the years, SAS has broadened the
scope of its activities to encompass all
areas of acoustics as well as several
related disciplines-such as physiology and
audiology. Initially, the activities of the
Society were concentrated in Stockholm
at the Royal Institute of Technology.
A topic was chosen for a SAS meeting,
a paper was presented and a lengthy
discussion followed. Later, the activities
were expanded to include Gothenburg and
Malmo, and indeed the whole of Sweden.
It has now become a tradition of SAS
to hold an annual meeting with several
lectures and a social function. In 1954,
SAS played an active role in the formation
of the Scandinavian Acoustical Society
(NAS), and the first meeting was held in
Copenhagen, Denmark, with Paavo Arni
from Finland as president. Members of
NAS (today NAM) are the four acoustical
societies of the Scandinavian countries.
The societies take turns hosting the
Scandinavian Acoustical Meetings. For
example, SAS hosted the Scandinavian
Acoustical Meeting (NAM 98) in
Stockholm during three days of September
in 1998 with Leif Akerlof as chairman.
SAS continues its involvement as a
society dedicated to spread knowledge in
the field of applied acoustics, particularly
as related to the noise problems in the
world. SAS is an active member society
of International INCE. In 1990, SAS
hosted INTER-NOISE 90 at the Chalmers
University of Technology in Gothenburg.
The number of registered delegates at that
congress exceeded 800 with participants
coming from 39 countries. The largest
delegation was, of course, from Sweden
with over 200 participants. With the
theme Science for Silence, the congress
was focused on the need for applied
science to support future improvements in
environmental noise levels.
For more information, visit us at
www.akustiska-sallskapet.org. NNI
Membership is open to all interested
parties who wish to promote acoustics
in Sweden. Members also receive
our newsletter each trimester and
information about activities organized or
sponsored by SAS. Online subscription to
Acustica Acta Acustica has been included
in the membership fee since 2011.

Public Outreach Workshop on Noise in
Communities and Public Areas
Darlene E. Kilpatrick, Lawrence S. Finegold, and David Sykes
INTRODUCTION
Noise is a significant social and public
health problem, particularly in urban
areas. Documented health effects include
hypertension, increased risk of stroke and
heart attack, sleep disturbance, speech
interference, annoyance, compromised
enjoyment of natural quiet, and a general
decrease in the quality of life (WHO
2011). Protected natural areas, flora and
fauna are also affected; noise exposure in
national parks and wilderness areas has
been documented by the US National Park
Service (NPS) (Reid and Olson 2013).
Successful resolution of these problems
requires informed public support for
improved noise management policy at all
levels of government.
One method of stimulating collaboration
and gaining public support is hosting free
public outreach workshops. On August 27th
2013, the public outreach workshop “Noise
in Communities & Natural Areas” was held
in Denver, Colorado, USA, and co-chaired
by Towards A Quieter America (now
“Quieter America” [QA]) and the NPS1.
The workshop was held concurrently with
the Institute of Noise Control Engineering
(INCE) Noise-Con conference. This was
the fourth in an ongoing series of free
public outreach workshops in the United
States on community and environmental
noise management organized by QA.
Previous public outreach workshops in
the US were held in Baltimore (2010),
Seattle (2011), and New York City (2012).
1 NPS does not endorse or promote any
product, conference, foundation, or
organization by their involvement in Public
Outreach Workshops.
2014 September www.inceusa.org
These free public workshops comply with
the National Academy of Engineering’s
(NAE) recommendation for organized
public outreach to educate & inform
Americans about exposure to noise, the
effects of noise, noise policy, and noise
control options (NAE 2010). The QA
workshops are endorsed by the National
Research Council Transportation Research
board/ADC40, The National Hearing
Conservation Association (NHCA),
INCE, the American Society of Heating,
Refrigerating and Air-Conditioning
Engineers (ASHRAE) Technical
Committee 2.6, and multiple American
National Standards Institute (ANSI)
Working Groups. Quieter America was
and continues to be chaired by Lawrence
Finegold and David M. Sykes with Darlene
Kilpatrick as the Executive Assistant.
The primary sponsor of the “Noise in
Communities and Public Areas” workshop
was the Michiko So Finegold Memorial
Trust (MSFMT) which also sponsors QA.
BACKGROUND: MICHIKO SO
FINEGOLD MEMORIAL TRUST
The MSFMT came to fruition following
the tragic loss of a dynamic, passionate,
and caring woman: Dr. Michiko So
Finegold. Michiko passed away suddenly
in 2011, entrusting her husband, Lawrence
Finegold, with her legacy. Mr. Finegold
established the MSFMT to honor his late
wife and continue their important work.
Michiko So was born in Tokyo, Japan in
1954 to a prominent and influential family.
She graduated from Nihon University
with a PhD in Engineering Science (Field
Study of Noise Effects and Community
• www.noisenewsinternational.net • www.i-ince.org
Evaluations Concerning Aircraft Noise)
in 1983. She served as a lecturer at Nihon
University from 1983-2000 where she
taught courses on various topics including
Neighborhood Noise and Insulation
Programs. She studied environmental
noise problems related to traffic, industrial,
residential and commercial areas. As a
result of her work Dr. So was awarded the
Institute of Noise Control Engineering,
Japan (INCE/J) Encouragement Prize
in 1987. During her career she made
significant contributions to identifying
and addressing a wide variety of noise
problems in Japan.
In 2000 Dr. So married Lawrence Finegold
and together they began to
work internationally as consultants on
noise effects research issues and noise
policy topics. In May 2010,
Dr. Michiko So Finegold, her husband
Mr. Lawrence Finegold, and Mr. David
Sykes formed what is now “Quieter
America” to organize outreach in support
of noise research and public policy. The
Michiko So Finegold Memorial Trust
collaborates with QA to stimulate public
interest in acoustical science and noise
control and to assemble scientific and
professional organizations into a joint
task force capable of having an effective
voice in public policy. Their focus is to
use scientific data to raise awareness on
the effects of noise and influence public
policy through outreach. In addition,
QA stimulates problem-solving through
dialogue with leaders in national and
international governments, government
agencies and NGOs. The foundations for
their current work are the publications
7
Burden of Disease From Environmental
Noise (WHO 2011), Technology for
a Quieter America (NAE 2010) and
Protecting National Park Soundscapes
(Reid and Olson 2013). These documents
provide the basis for a profession-wide
strategic road map for acoustical science
and noise control engineering.
WORKSHOPS
Each public workshop tailors its topics to
be relevant to the communities in which
they are held. For example, cities in
Colorado such as Denver and Colorado
Springs have progressive noise regulations
to protect their health and wellbeing as
well as the sanctuary of the mountains and
open spaces. Over 150 people participated
in the Denver workshop. Participants
included concerned citizens, employees
of the NPS, the US Forest Service, nongovernmental organizations, city/state
government officials, and INCE members
from the concurrent Noise Con conference.
Presenters included international scientists,
INCE and QA members, university
researchers, naturalists and public figures.
Topics included the effects of noise on
human health, current noise policy, recent
research and potential solutions. Issues
such as quiet in natural areas and the loss
of natural sound were addressed through
the vital collaboration with NPS; primarily
by Dr. Kurt Fristrup, Branch Chief for
Science and Technology in the Natural
Sounds and Night Skies Division of
Natural Resource Stewardship and Science.
The workshop offered a unique forum
where noise experts, Noise Con attendees,
and the public could interact. The
public format allowed engineers and
policy-makers to hear what is important
and where our current regulations or
technologies fail the average citizen.
Presenters and INCE members dialogued
with the public on steps they could take
to reduce noise and increase quality of
life. The workshop was divided into three
8
sessions: morning, afternoon and evening,
with multiple keynote speakers. Each
session was followed by a question and
answer period with the presenters from that
session and the attendees.
SUMMARY OF
PRESENTATIONS
The morning session began with the
introduction of the keynote speakers by
QA chair Lawrence Finegold. The morning
keynote speakers were Dr. George Maling
(chair of the committee that produced
Technology for a Quieter America [NAE
2011]) and Eric Wood (past president,
INCE-USA). Dr. Maling summarized key
sections of the Technology for a Quieter
America report and emphasized the
chapters on community noise, metrics for
the assessment of environmental noise, the
role of government and public information
on noise control. Mr. Wood presented the
difficulties of enforcing motorcycle noise
ordinances at state and local levels. He
also discussed potential solutions through
education and behavior modification. This
was followed by QA chairs Lawrence
Finegold and David Sykes. Mr. Finegold
discussed community-based environmental
noise management, such as techniques
available to local communities and
governments to take pre-emptive and
mitigating actions to reduce community
noise. Mr. Sykes reviewed past and current
national noise policies, the challenges
associated with revising them and the
importance of updating these policies
after decades of neglect to increase their
relevance in today’s society.
The afternoon session began with
introductions by QA chair David Sykes.
The first presentation was by Bennett
Brooks (Brooks Acoustic Corporation)
who summarized the ANSI standards and
provided guidance for the development of
local noise ordinances that are appropriate
for local circumstances. Mr. Brooks
suggested that local ordinances should
provide a technical basis to manage
the local sonic environment and help
communities decide which sources of noise
need to be regulated to have an improved
acoustical quality of life. Following
Mr. Brooks, Nicholas Miller (Harris,
Miller, Miller and Hanson, Inc.) discussed
the complexities involved with defining,
assessing, improving and preserving quiet
areas. Mr. Miller also postulated that many
of these difficulties are associated with
differing human interpretations about what
types of noise are considered desirable
or undesirable in natural areas. This was
followed by Dr. Jessie Barber from Boise
State University who presented recent
research on how traffic noise influenced
habitat use by birds to where some habitats
that were otherwise suitable were excluded
solely due to the influence of vehicular
traffic noise (Francis and Barber 2013).
Dr. Barber also discussed how increased
anthropogenic noise can be detrimental to
the survival of many bird species. Eddie
Duncan (Resource Systems Group, Inc.)
discussed how he used public input to
develop scientifically sound noise pollution
policies for Vermont’s rural communities
and the importance for the community
input. Jan Jabben (National Institute for
Public Health and the Environment, the
Netherlands) talked about the importance
of preserving and improving the areas of
natural quiet such as urban parks and open
spaces, particularly in densely populated
areas. He discussed a study that rated
public opinion on the accessibility and
quality of urban parks and open spaces and
how such data can be used to influence
policy. Les Blomberg (Executive Director,
Noise Pollution Clearinghouse) gave the
final presentation of the afternoon session
where he discussed how industrialization,
particularly increased vehicular and aircraft
traffic, has greatly reduced natural quiet.
Mr. Blomberg presented a model to predict
which public land had the highest level of
natural quiet based on minimal amount of
vehicle and aircraft traffic.

September
The evening session began with
introductions of the keynote speakers by
QA chair Lawrence Finegold. The evening
Keynote Speakers were:
Dr. Arline Bronzaft, Dr. Kurt Fristrup, Julie
Zickefoose and Erik Lindbergh.
Dr. Bronzaft discussed her research on
the adverse impacts of noise on children’s
classroom learning and the adverse effects
of noise on mental and physical health. She is an author of “Why Noise Matters:
A Worldwide Perspective on the Problems,
Policies and Solutions” (Stewart and
Bronzaft 2011). Dr. Kurt Fristrup from the
NPS presented research on noise levels in
national parks and the need to preserve the
natural sounds of national parks.
Dr. Fristrup talked about acoustical
conditions in various national parks and
presented models predicting sound levels
throughout the continental U. S. He also
discussed the coordination of NPS with the
aviation industry to reduce air traffic over
national parks. Radio host and renowned
naturalist Julie Zickefoose talked about
the basic human need for connecting to
nature and wildlife, which she captured
in her 2012 book, entitled: “The Bluebird
Effect: Uncommon Bonds With Common
Birds.” The final speaker of the workshop
was aviator and entrepreneur Erik
Lindbergh, grandson of the famed aviator
Charles Lindbergh. Erik Lindbergh was an
inspirational speaker who shared how he
triumphed over adversity, reminding us that
even in the face of seemingly impossible
odds one can persevere through hard work,
commitment and dedication. His current
challenge and quest is to move the future
of flying toward the use of electric aircraft
to reduce aviation noise.
SUMMARY OF PUBLIC
COMMENTS
There were numerous questions and
comments from the attendees - too
numerous to be included in this paper.
However, we will summarize the most
common questions and concerns. Common
2014 September www.inceusa.org
complaints were about railroad noise and
loud music from vehicles during nighttime
hours. The railroad issue was in regards
to the mandatory use of the horn when
traveling through urban areas, which
typically occurs at night when there is less
vehicular traffic. The question arose from
a local nurse who expressed concern that
such noise could result in health issues.
The panel explained that this horn use
was initially developed for rural areas
and that exemptions could be granted to
individual communities. The loud music
from “boom cars” was a challenging issue
as local law enforcement officers are not
provided with the means or personnel to
measure the decibel level and enforce local
ordinances. A panel member suggested
that even if local law enforcement were
able to measure the decibel levels, federal
regulations are so technical they become
impractical and prohibitive.
There was an expression of overall
frustration about the apparent lack
of interest and apathy on the part of
federal regulatory agencies regarding the
issues of noise, particularly compared
with current published research and
policy coming from Europe. The panel
explained that the difficulty in the US is
that there is no longer a single federal
agency responsible for monitoring
noise issues. There are several agencies
that have taken matters into their own
hands. However, the current challenge
has become one of counterproductive
“turf wars” between these different
agencies. Different measurement methods
and metrics are used by the individual
agencies resulting in inconsistent and
incomparable results and little to no interagency communication. It was suggested
by the panel and attendees that most
of the general public has the ability to
measure noise levels through applications
on their mobile telephones. And while
such measurements may not be consistent
among individuals, “crowd sourced” data
• www.noisenewsinternational.net • www.i-ince.org
could provide a meaningful and significant
foundation on which to build a larger body
of scientific evidence to present to
policy makers.
Not all comments were those of doom
and gloom and several success stories
were shared. For example, in Estes
Park, Colorado a league of women
voters became concerned about the
noise associated with commercial tourist
aviation over nearby Rocky Mountain
National Park. These women educated
themselves on the issues of noise and
local noise ordinance, engaged the public
and were successful in proposing a ban
on local air tourism which was enacted
by the Colorado State Legislature. An
attendee from Maine shared the successful
upholding of noise limits on farm wind
turbines in his local community through
thoughtful discussions with local city
planners. A panel member also pointed out
the establishment of acoustic guidelines for
schools. An overarching theme was that
change needed to begin at the local level
and that enacting and enforcing local noise
ordinances would likely solve many of
the problems.
THE FUTURE OF QA
AND MSFMT
The Michiko So Finegold Memorial Trust
and QA will continue to offer free public
workshops to gain public awareness
and support. The 2014 Noise Con in
Ft Lauderdale, Florida will host the next
QA public workshop. The workshop will
focus on the effects of noise on marine life
and birds.
Lawrence Finegold and David Sykes
continue to be active and influential
participants in INCE, ICBEN, and other
noise related organizations. The MSFMT
will offer its first medal to award scientific
excellence in advancing the quality of life
through scientific research on the effects of
noise at the International Congress on the
9
Biological Effects of Noise in Nara, Japan,
in June 2014. Quieter America and MSFMT
are also collaborating with Transcends
Films to assist with the production of a
documentary film on the effects of noise
called “The Pursuit of Silence”.
Quieter America believes in order to
influence governments, agencies and
NGOs, it is essential for established
professional organizations to form an
organized joint task force with shared
goals that can awaken and catalyze public
concern. These organizations must speak
with one voice. To achieve these goals,
MSFMT and QA are encouraging relevant
professional societies to meet and agree
on a shared agenda. The ultimate goal is to
meet with US policymakers and create new
policies and regulations that make the US a
leader in noise policy once again.

General Overview of JAFOE
Engineers specializing in noise control
and acoustics gathered with young
engineers from several other fields of
engineering for the 2014 Japan-America
Frontiers of Engineering (JAFOE)
Symposium held in Tokyo, Japan June
9-11, 2014. The event provided an
opportunity for the engineers who are
early in their career (between 30 and 45
years old) to discuss the state of noise
control engineering and the frontiers of
future research and application.
The JAFOE event is organized and hosted
by the National Academies of Engineering
for both the US and Japanese nations.
This most recent JAFOE event was the
8th time for these two organizations to
meet and discuss the latest information
on four topics in engineering. Along with
the session on Noise Control Engineering,
this year’s session topics also included
Bioimaging, Power Unplugged: Energy
Harvesting and Power Transmission, and
Field Robotics for Disaster Response
(a longer description of each of these topics
and the presentations on the individual
topics are available at the JAFOE 2014
website: http://www.naefrontiers.org/
Symposia/JAFOE/32546/41283.aspx).
Each topic included two invited speakers
from each country to present their latest
research and insights on the topic. This was
the first time that noise control engineering
had been discussed. We appreciate this
year’s inclusion to the support from Proctor
Reid at the US National Academy of
Engineering and the generous financial
contribution of Lawrence S. Finegold and

General Overview of Noise Control
Engineering Session
From JAFOE
The Noise Control Engineering session
was organized by Hiroshi Sato from the
National Institute of Advanced Industrial
Science and Technology in Tsukuba,
Japan and Jeff Fullerton from Acentech
Inc. in Boston, MA. Mr. Sato and Mr.
Fullerton invited experts in the field of
noise control engineering to discuss the
topic of Noise Control Engineering in
Healthcare Environments. The invited
speakers included Shinichi Sakamoto
from the University of Tokyo, Erik MillerKlein from SSA Acoustics in Seattle, WA,
Mandy Kachur of Soundscape Engineering
in Ann Arbor, MI, and Hiroko Terasawa of
Tsukuba University, Tsukuba, Japan.
Mr. Sakamoto presented his research and
findings on the prediction, control and
assessment of environmental noise. During
his discussion, he focused on roadway and
wind turbine noise assessments, which
are issues that affect the public in Japan.
Mr. Miller-Klein discussed the changes
to the healthcare systems in the United
States and how acoustics and noise control
will influence these changes. He cited
research showing the link between low
patient survey scores and the acoustical
conditions in the healthcare environments.
Ms. Kachur spoke further about acoustics
in healthcare environments and what
can be done to improve the outcomes
of patients and reduce the stress and

studies showing how improved acoustical
conditions have been implemented on
recent healthcare facility projects. Mrs.
Terasawa presented her research of
sonification, where bioelectric signals
and data are used to provide a positive
and motivating feedback mechanism for
rehabilitation patients. She also showed
events where sonification of physiological
data was used to produce modern music
and art. The abstracts for each speaker that
were submitted for the event appear on the
following pages.

The noise control engineering presentations
generated positive feedback and intriguing
questions about the further uses of the
research and findings for improving the
quality of life. The US NAE event organizer
said she was not sure why the topic of noise
control engineering had not be discussed in
previous JAFOE events and that it should be
included as a topic again in the future.

Technologies on Environmental Noise
Issues in Japan
Shinichi Sakamoto, University of Tokyo, from JAFOE
Environmental noise issues,
transportation noises from road traffic,
railways and aircrafts have been typical
problems so far. Among them, the
author has been studying prediction and
countermeasure of road traffic noise.
The prediction methods of noise by
computation are roughly categorized
in two areas; the one is an engineering
method on energy-base and the other is
a precision model based on wave theory.
Through research on energy-based
calculation method, the author has been
concerned with development of ASJ
14
RTN-Model, which is now used as the
standard engineering calculation model
for environmental noise assessment in
Japan. In my presentation, the noise
prediction model is firstly introduced.
Originally the author studied wavebased numerical analysis on acoustics.
Although the application of the wave-based
numerical analysis is limited because it
focuses on a comparably detailed area,
the method can be efficiently used as a
tool for precision modeling of road traffic
noise. Furthermore, the method also can
be utilized for the development of the
engineering model. Such applications of
the precision model are also introduced.
As a novel environmental noise issue,
wind turbine noise problem is being
concluded. The author dealt with the
issue and performed psycho-acoustical
experiments. The outcome of the research
will be introduced, and the current situation
and the future developments of noise
mitigation technology will be discussed.

Acoustics and the Patient Experience
Erik Miller-Klein, PE, SSA Acoustics, LLP, from JAFOE
The Hospital Consumer Assessment
of Healthcare Providers and Systems
(HCAHPS) surveys have brought
increased focus on noise control
engineering for healthcare environments. This survey asks a series of questions to
recent hospital patients, and the scores
have a direct impact on the facilities rating
and the government reimbursements
for medical services. The HCAHPS
survey has one question on noise; “how
often was the area around your room
quiet at night?” This question does not
lend itself well to normal noise control
design metrics or mitigation design
considerations. This has led designers,
researchers and engineers to explore the
connections between patient experience,
and the noise control impacts that lead
to improved scores, medical outcomes,
and performance. This question requires
a balance between psychoacoustic and
effective noise control design to optimize
healthcare environments and patient
health.
Hospitals are unique and complex
acoustic environments filled with
numerous noise sources, limited by strict
hygienic requirements, and populated
with critically sensitive occupants.
Healthy soundscapes are paramount to
the missions of hospitals: patients need
to sleep and heal without environmental
stressors; staff, patients, and family need
to communicate accurately but privately;
staff need to be able to localize alarms
and calls for help. Numerous studies

Erik Miller-Klein speaking about the latest drivers for improved acoustics in healthcare
environments in the US.
show that hospitals are unacceptably
noisy. There is also evidence to suggest
that poor hospital soundscapes can be
detrimental to occupants. For example,
noise in hospitals has been suggested to
increase patient risk for cardiovascular
response, pain, intensive care delirium,
fragmented sleep, and reduced
recuperation. Highlights will include
projects relating noise, room acoustic,
medical equipment noise and alarms, and
spatial layout metrics to staff and patient
response in addition to studies evaluating
• www.noisenewsinternational.net • www.i-ince.org
impacts of acoustic retrofits. Results show
that effective hospital soundscapes require
a complex choreography of architectural
layout, acoustic design, medical
equipment and alarms, and administrative
processes that is only beginning to be
fully understood.

Managing Noise in Healthcare Environments
to Benefit Patient Outcomes
Mandy Kachur, PE, INCE. Bd. Cert., Soundscape Engineering LLC
Unnecessary noise, then, is the most cruel absence of care
which can be inflicted either on sick or well.
Florence Nightingale, 1859
In the 150 years since Florence Nightingale
wrote about the adverse effects of noise
on hospital patients, others have noted the
problem, but it is still not recognized as a
major cause of patient harm. Noise control
in U.S. healthcare environments has
grown as a priority after the publication
of landmark papers in 2004, documenting
the gradual and detrimental rise in
worldwide hospital noise levels since 1960
and the resulting noise-related medical
errors. Consequently, noise in healthcare
environments is becoming recognized as a
serious health issue, increasing staff stress
and absenteeism, hindering patient healing,
and causing patient injury and fatalities.
In the U.S., new regulations and financial
incentives have been put in place in the
last five years. Since October 2013,
government reimbursement to hospitals
is adjusted based on the scores of a
standardized patient assessment survey,
on which noise is consistently rated
worse than any other category. Also, the
Joint Commission, an independent, notfor-profit organization that accredits and
certifies healthcare facilities, has made
alarm safety a national patient safety goal
starting in 2014, signaling that hospitals
must give it top priority. Regarding the
built-environment, the 2010 edition of the
Guidelines for the Design and Construction
of Health Care Facilities, a document used
or referenced in 42 American states and
in 60 countries, has a greatly expanded
acoustics section covering a wide range of
16
topics from acoustical finishes and sound
isolation to paging systems and noiserelated safety risk reduction. Furthermore,
sustainable building design initiatives,
which have become increasingly popular
in the U.S., have included acoustics as a
design consideration since 2009.
Noise engineers and medical personnel
generally had been working separately
on noise issues, with limited progress
and implementation of their findings.
With the new urgency for improvement,
multidisciplinary teams have been
formed to produce actionable research
and evidence based design initiatives.
This collaboration between medicine
and engineering has produced data on
physiological responses, healthcare
outcomes, and economic impact, which
all have more influence on policy making
than the historic assumption that noise is
nothing more than an annoyance. While
progress has been made in the builtenvironment, changing healthcare worker
behavior and the healthcare culture has
proven to be more challenging.
Though obtaining funding for these
studies presents challenges, a growing
body of research about the harmful effects
of noise in the healthcare environment
along with the new financial and
regulatory incentives has advanced noise
control in healthcare facilities to a top
priority. The end goal is improving patient
outcomes, increasing staff comfort and
establishing a healthy environment for all.

Acoustical Applications to Healthcare
Hiroko Terasawa, Tsukuba University
Sound is a medium that connects inside
and outside of human being. People
observe and understand the surrounding
environment by listening to sounds,
and express our response back into the
environment by making sounds. Our data
sonification project borrows this paradigm:
We represent biological information with
synthesized sounds so that people can
intuitively understand and respond to
the data in an embodied and enjoyable
manner.
In this talk, I will present our research
on (1) auditory biofeedback system for
physical therapy and (2) brain wave
sonification for multi-channel EEG data
analysis.
By listening to his/her own motion, people
can move more efficiently and easily. Our
auditory EMG biofeedback system (AEB)
transforms the muscular movement data
into sound in real-time, to help blind and
sighted people undergo physical therapy
with better control and comfort. In the
evaluation test, blind people conducted a
gripping task more accurately and easily
with AEB, while sighted people also
reported increased easiness with AEB.
Another experiment showed that both
auditory and visual biofeedback systems
offered comparable efficiency in helping
ankle-joint rehabilitation task even for
sighted people.
2014 September www.inceusa.org
Sonification is valuable as data analysis
tool as well: With our EEG data
sonification, people without knowledge
of neuroscience easily detect the presence
of a special kind of brain activity
(steady state responses). Furthermore,
the synchrony across EEG channels and
the location of strong activity are precisely
understood by sonification: Our evaluation
test showed that subjective judgments
with sonification were in agreement with
the results of statistical analysis. These
studies suggest that sonification can be
an intuitive alternative for EEG data
analysis to meticulous computational
methods.

Finding Europe’s Quiet Areas
At least 110 million people are adversely
affected by noise from Europe’s busiest
roads alone. People need to escape this
pollution and access quiet places to work,
relax and live a healthy life. Such ‘quiet
areas’ should be protected under EU
legislation, but how does this work in
practice?
When we think about noise pollution,
we often think about loud music or a
neighbor’s barking dog. But in most
cases, the real health problems are caused
by long-term exposure to noise from road
traffic, railways, airports, or industry.
A quiet area is not necessarily silent,
but rather one that is undisturbed by
unwanted or harmful sound created
by human activities, according to the
2002 Environmental Noise Directive.
Indeed, some types of noise such as the
sound of running water or birdsong are
usually perceived as enjoyable. This
means that it may not be possible to define
a quiet area by just measuring decibels.
A new European Environment Agency
(EEA) report, ‘Good practice guide on
quiet areas’, provides guidance and
recommendations for authorities who
need to identify and maintain these places.
Its publication marks International Noise
Awareness Day, 30 April 2014.
Hans Bruyninckx, EEA Executive
Director, said: “When we think about
noise pollution, we often think about loud
music or a neighbour’s barking dog. But
in most cases, the real health problems
are caused by long-term exposure to noise
from road traffic, railways, airports or
industry. Quiet areas are important because
they can provide respite from noise,
ultimately improving quality of life.”

Another approach to the problem of
noise is the idea of soundscapes, creating
healthier and quieter environments. The
European Soundscape Award 2014 aims
to draw attention to the most innovative
product, campaign, innovation or scheme
solving a noise problem.
The award is a joint initiative of the
European Environment Agency (EEA)
and the Noise Abatement Societies of the
Netherlands and UK. The deadline for
submissions is 18th August 2014. More information.
Noise App
The EEA has developed NoiseWatch,
an app which measures and maps
noise levels. Over the last two years,
NoiseWatch has received more than
155 000 citizens’ noise ratings from
around the world. On 8 May, the EEA
received a World Excellence Award for the
app at the Geospatial World Forum.
Coming Up
Later in 2014, the European Environment
Agency will publish its first Europe-wide
noise assessment report. It will draw on
data from Member States, highlighting
the main sources of noise in Europe as
well as its impacts on health and the
environment. EuroNoise2015:

Quiet, Please! Hong Kong Is
Suffering from Severe Noise
Pollution.
By Albert Lin
Hong Kong is too noisy because, as
a rule of thumb, not only are some
members of our industrial, construction
and commercial sectors uncaring about
the noise their operations create, but too
many of our flat-dwelling residents are
seemingly deaf to the noise they generate.
The root cause of today’s noise pollution
in Hong Kong is poor planning in the
past coupled with cramped development.
With its limited land supply Hong Kong’s
expansion had only one way to go—
upward. But each high-rise added to
population density involving ever greater
numbers of people crammed into
multi-story accommodation on either side
of the harbor.
And so, to accommodate increasing
road traffic, we saw the construction of
elevated highways that in some cases
run just outside families’ living rooms,
which brings us to our biggest single
noise problem today—noise pollution
from traffic, affecting more than 1 million
people. And the reason for our noisy
roads is that Hong Kong has a gross
imbalance of motor vehicles compared
with road supply. These statistics put
it very plainly—there are 318 licensed
vehicles for every kilometer of road, and
70 percent of all vehicles on our roads are
private cars—a total of 464,595 of them.
Happily, more than 30 km of barriers
and screens have been erected along our
new roads since 1990, providing a buffer
against traffic noise for New Territories
residents living nearby. Specially paved
low-noise road surfaces are also being
22
used to reduce traffic noise. But such
noise-amelioration measures simply
cannot be applied to old, existing urban
roads, except if they are to be
re-surfaced—which would in turn involve
major traffic diversions.
Returning to our noisy industrial/
commercial operations, sometimes the
explanation is that noise-mitigation
measures haven’t been fully introduced
because they cost money and affect
the company’s profits. Often only the
barest possible steps are taken, prodded
along by prosecutions launched by the
Environmental Protection Department
(EPD). Although set up in 1986, the EPD
only got its “teeth” three years later, when
the Noise Control Ordinance was passed. This empowered its inspectors to take
offenders to court as they struggled to
get a grip on the runaway noise pollution
that was beginning to seriously affect our
living standards.
The worst offenders in those days
were the builders’ pile drivers crashing
away to create the solid foundations of
construction projects. Unremittingly they
thumped away at least 12 hours a day as
our economy boomed and residential and
commercial developments blossomed
across the urban areas.
Today pile-driving is limited to three to
five hours a day in built-up areas, quieter
machinery must be used and various
noise-abatement procedures exercised
on site. Nevertheless some anti-social
construction companies still flout the
regulations and seem to regard fines for
noise offences as an overhead.

2014 Japan-America Frontiers
of Engineering Symposium
The 2014 Japan-American Frontiers of
Engineering was held June 9–11, 2014,
in Odaiba, Tokyo, Japan. Sixty of the
most promising engineers under the age
of 45 from Japan and the United States
met for an intensive 2-1/2 day symposium
on developments at the cutting edge of
engineering technology in four areas:
Field Robotics for Disaster Response,
Power Unplugged: Energy Harvesting
and Power Transmission, Noise Control
Engineering in Healthcare Environments,
and Bioimaging. The event is intended
to facilitate international and crossdisciplinary research collaboration,
promote the transfer of new techniques
and approaches across disparate
engineering fields, and encourage the
creation of a transpacific network of
world-class engineers.
The National Academy of Engineering
would like to express its gratitude to
the following sponsors for their support
of the 2014 JAFOE Symposium: The
Grainger Foundation, the Japan Science
and Technology Agency, Lawrence S.
Finegold and the Michiko So Finegold
Memorial Trust, and the National Science
Foundation.

China Punishes 19,289
Environmental Violations
As China cracks down on environmental
violations, authorities handed out
punishment in 19,289 cases in the
first half of the year, the Ministry of
Environmental Protection said on
Tuesday. Violators were fined a total of
743.25 million yuan ($121 million), the
ministry said in a statement. According
www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014
September
to the ministry’s statistics, East China’s
Zhejiang province tops the punishment
list with 4,077 cases punished and 187.22
million yuan of fines in the region. Six
other regions including Beijing, Hebei
and Jiangsu saw more than 1,000 violators
punished respectively.
the ministry published a circular to
promote the supervision over government
enforcers’ work in environmental
regulation enforcement.
The ASC Hosted ICSV21 on
July 13–17, 2014, in Beijing
Environmental authorities at all levels
transferred 861 cases of suspected
environment-related crimes, such as
discharging heavy metal or persistent
organic pollutants, to the police for
criminal investigations. Also on Tuesday,
The 21st International Congress on
Sound and Vibration (ICSV21) was
successfully held by the Acoustical
Society of China (ASC) and the Institute
of Acoustics, Chinese Academy of
Sciences (IACAS), under the aegis of the
IIAV on July 13–17, 2014, in Beijing,
China. Professor Tian Jing, the president
of the ASC, was the general chair. The
theme of this congress was “In Depth
Sound and Vibration Research.” With
841 representatives from 50 countries
2014 September www.inceusa.org
• www.noisenewsinternational.net • www.i-ince.org
A majority of cases involved violations in
environmental evaluation, with water, air,
solid waste and noise pollution also high
on the list.
and regions, 672 technical papers
and 580 oral presentations (6 plenary
sessions and 16 parallel sessions), and
41 exposition booths, the ICSV21 was
the largest annual congress ever. The
ICSV22 will be held in Florence, Italy,
on July 12–16, 2015.
ICA congress proceedings
Most of the past ICA proceedings have
been scanned by the Acoustical Society
of China (ASC) and will be available
online on the current ICA website
at http://www.icacommission.org/
proceedg.html. The Proceedings of these
Congresses will be presented to have a
freely available archive. Many thanks
to Professor TIAN Jing for this massive
undertaking. NNI

The Moral Status of
Technical Artifacts
Peter Kroes and Peter-Paul Verbeek
Editors, Springer V.17 of Philosophy of
Engineering and Technology, Springer, NY,
(2014), 248 pp., 129.00 USD,
ISBN 978-94-007-7913-6
The Moral Status of Technical Artefacts is
a 13 chap­ter book discussing the morality
of technology. It has a very interesting
concept: can the influence of technology
on human actions and decisions be
considered mor­ally good or bad, or is it
the technology itself that has some moral
value? Are technical artifacts (machine
guns, electric chairs, nuclear bombs) just
passive instru­ments to be used for good or
bad or does their very ex­istence actively
shape the human condition? Another way
of putting it is: are the morally positive
(or nega­tive) aspects of technology due
to the way humans use it or the way
technology affects human life? No clearer
example of the latter is the ubiquitous use
of cell phones in airplanes, classrooms,
bus stops, and so on. The editors note
that stories that stress the positive aspects
of technology tend to praise humans for
their astute use of technology while those
stories stressing the negative aspects place
blame on the device(s). So the issue is
whether artefacts are particularly good or
bad agents.
In the past, and traditionally thought,
there was no is­sue. Only acts of agents, or
agents themselves, would be considered
morally good or bad. (I am leaving out
the possibility that some sort of “god”
determines anything.) The thing, artefact,
used was inconsequential. In a way, this
makes sense for we would have problems
calling a stop sign good and a gun bad.
2014 September www.inceusa.org
But then, it is clear that technical artefacts
do influence human behav­ior. (Hmmm.
Here is a semi-automatic rifle, I need to
make a statement, and I will go to the
school and kill a bunch of kids and then
myself. That will show them.)
So, if technical artefacts do affect actions,
maybe they can be thought of as morally
good or bad. But keep in mind that
technical artefacts are things built by
people for some purposes, or some ends,
and these ends cannot be separated from
the artefact.
List of the 13 chapters, done by a variety of
authors, including some by the editors:
1. Introduction
2. Agency in humans and in artefacts: a
contested discourse
3. Towards a post-human intra-actional
account of sociomaterial agency (and
mortality)
4. Which came first, the doer or the deed
5. Some misunderstandings about moral
signifi cance of technology
6. “Guns don’t kill, people kill”: values
in and/or around technologies
7. Can technology embody values
8. From moral agents to moral factors:
the structural ethics approach
9. Artefactual agency and artefactual
moral agency
10. Artefacts, agency, and action schemes
11. Artefactual agents and their moral nature
12. The good, the bad, the ugly...and
the poor: instrumental and noninstrumental values of artefacts
13. Values in chemistry and engineering
• www.noisenewsinternational.net • www.i-ince.org
The chapters are condensed and references
follow each. The book does not provide
answers but rather a compi­lation of
arguments (to me, both sides legitimate)
on the morality of artefacts. For example,
should some arte­facts be destroyed
because, by themselves, they are “bad”
like ICBMs, nuclear power plants(?), and
chem­ical weapons? Lots of people would
agree. Similarly, do people kill people or
do guns kill people? In a way, both are true.
The Moral Status of Technical Artefacts
is a tough but great read. But it is an
important book, for it gives in­sight as
to the role of what we as engineers produce
and how that is used, in a moral sense,
by our customers.
Highly recommended.

Animal Communication
and Noise
Henrik Brumm Editor, Series: Animal
Signals and Communication, Vol. 2,
Springer, New York NY, (2013), 453 pp.,
189 USD, ISBN 978-3-642-41493-0
The book, Animal Communication
and Noise, which is edited by Henrik
Brumm, is a great resource for ad­vanced
undergraduates, graduate students and
profes­sionals who have an interest in how
animals solve the issue of communicating
in noisy environments. It is a handy
reference for those interested in how
animals deal with the natural world and the
noise in which they have evolved, as well
as how they attempt to compen­sate for a
world of increasing noise pollution.
27
The book begins with a short review of
signal detec­tion theory and presents the
premise for the evolution of communication
as it relates to both the animal produc­
ing the signal, the intended receiver and
the potential for errors in communication
between the two. This is followed by a
number of chapters on the most apparent
condition of the communication-in-noise
problem, that of acoustical communication.
Examples of challenges faced by the
signal producer and the receiver, as well as
solutions to those challenges, are provided
for insects, fish, anurans, birds and marine
mammals. The Lombard effect, frequency
shifting, temporal variation in calling and
comodulation masking release are but
a few of the topics discussed in various
animal-specific contexts which is useful
for understanding how these generalized
phenomena vary in use by the niche that
each animal exploits. Not to be overlooked,
the book also contains several chapters
addressing communica­tion in noise from
a perspective of visual, electrical and
chemical communication.
The book concludes with a chapter
on the issue of anthropogenic sound
and conservation. The chapter rightly
opens discussion of the issue from the
different perspectives of conservation
and anthropogenic noise in the terrestrial
and marine environments. The marine
environment has received more attention
than terrestrial environments in this regard
which might seem surpris­ing given the
relative ease with which habitat perturba­
tion can be seen in terrestrial habitats.
Yet, sound travels much more effectively
underwater than in air and some marine
organisms may have acoustic active spaces
that range in excess of tens of kilometers,
well beyond the air-borne acoustic range
of terrestrial mammals. Couple this with
some of the dramatic stranding events
involv­ing charismatic whales exposed
to high-powered sonar systems and it is
easy to understand how public opinion
has more aggressively pushed noise the
28
conservation effort in the oceans. The
chapter discusses the various approaches
to trying to determine how anthropogenic
sound impacts animals including a
discussion of several specific models
currently employed. The difficulties of
relating acoustic disturbances to predicting
biological impacts to individuals and
populations are presented and subsequently
linked to mitigation and management
practices. The inherent difficulty of
mitigation and management, in light of
little supporting scientific in­formation, is
an important topic of study for any scien­tist
interested in the noise pollution issue.
This book is an excellent resource for
individuals in­terested in the emerging issue
of the impact of anthro­pogenic sound on
animals, those interested in how animals
have evolved to mitigate noise interference
in communication and comparative
biologists and bio­acousticians interested in
evolutionary solutions to noise across taxa.
The book has a place on my bookshelf
right next to Marine Mammals and Noise
and comple­ments it well with the updates it
contains on the ocean noise issue.

Architectural Acoustics,
Second Edition
Marshall Long
Academic Press/Elsevier, (2014), 929 pp.,
hardbound, 119.95 USD,
ISBN 978-0-12-398258-2
This book is a thorough compilation of
acoustic prin­ciples and applications for
room acoustics, sound isola­tion, noise
control and sound reinforcement systems.
From the author’s preface, the book’s goal
was to pro­vide an organized approach
to acoustic interactions combining
theoretical background and practical
exam­ples to enable an intellectual
framework for thinking about the subject
matter. Architectural Acoustics admi­rably
attains this goal.
I have used the first edition of the book
since 2006 for my Architectural Acoustics
and Noise Control clas­ses at Peabody
Institute of Johns Hopkins University. The
book has been well received by students
and the chapter topics are logically
organized to enable effec­tive teaching.
Of particular note is the presentation of
data and figures, all which use the same
graphical for­matting, giving a unified
appearance that is easy to comprehend.
The book comprises 22 chapters arranged
in a logical sequence starting with
historical perspectives, progres­sing to
acoustic and perceptual fundamentals,
outdoor sound propagation, sound
isolation, mechanical vibra­tion and noise
control, room acoustics applied to differ­
ent building types, sound reinforcement
systems and finally acoustic modeling.
The first chapter covers acoustic history,
starting with the Greeks, with a primary
emphasis on religious and music
performance buildings and featuring prece­
dent setting examples.
Chapters 2 and 6 review acoustic
fundamentals to in­clude a general
description of sound, source character­
ization, levels and loudspeakers to aid
readers with the chapter topics that follow.
It would seem apt that the material in
Chapter 6 might better follow Chapter 2.
Basic psychoacoustics is presented in
Chapter 3 with emphasis on loudness,
speech intelligibility, health and safety and
audibility of sound reflections enabling
read­ers to understand the perceptual
implications of acous­tic design.
Chapter 4 addresses acoustic measurements
and metrics to include basics of
www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014
September
microphones and sound level meters,
quantifying environmental noise and an
introduction to specialized measurements
such as time delay spectrometry, sound
intensity and speech intelli­gibility. My one
criticism here is the over reliance on RASTI
for speech intelligibility assessment. Work
by Peter Mapp and others have shown this
metric not to be as accurate as the full STI
or abbreviated STIPA metrics.
Chapter 5 reviews environmental noise
with a partic­ular emphasis on exterior
sound propagation, barriers and traffic
noise modeling. Of interest is the thorough
description of sound absorption by air.
Sound reflection and absorption are the
topics of Chapter 7 with emphasis on coherent reflections, reflec­tions from finite
objects, absorption mechanisms and
special sound absorbers such as panels and
resonators. Sound reflections from ceiling
panel arrays are covered based on the work
of Rindel.
Chapter 8 is a logical sequence to the
previous chap­ter and describes the theory
of sound propagation in enclosed spaces,
starting with one-dimensional pipes and
ducts and progressing to three-dimensional
spaces with explanations of room modes,
diffuse field theory sound propagation,
reverberation equations and examples
where deviations from diffuse field
behavior occur.
Chapters 9 and 10 cover sound
transmission loss properties and sound
transmission in buildings. This re­viewer
has found these two chapters to be one of
the best presentations of these topics in
an acoustics book. Chapter 9 addresses
sound transmission loss theory for various
idealized panel configurations. Chapter 10
is more practical and covers sound
transmission for vari­ous conditions:
reverberant-to-reverberant, free field­
to-reverberant and transmission into
2014 September www.inceusa.org
absorptive spaces and through large
openings. A unique feature is the treatment
of the direct field transmission component
for reverberant conditions and sound
levels near and re­mote from the radiating
surface. One minor criticism is the use of
the term “R” for transmission loss which
is not consistent with North American
nomenclature.
Vibration and vibration isolation are the
subjects of Chapter 11. Its placement in the
book, between chap­ters on airborne sound
transmission and structure-borne sound
transmission may seem out of place but
makes sense as approximately one-fourth
of this chap­ter addresses floor vibrations
from human activities. The theory of
single and double degree of freedom
vibration-isolated systems is reviewed,
along with practical applications of
vibration isolator selection for mechanical
equipment and support of vibrationisolated equipment.
Chapter 12 covers noise transmission in
floor sys­tems with review of airborne,
impact and floor squeak noise. An
interesting aspect of this chapter, which
dif­fers from other acoustics books, is
separating impact noise from walking
into footfall and structural deflec­tion
components. These discussions, plus
the cited references, have provided new
understanding of these transmission
mechanisms to this reviewer. Now I know
the cause of those pesky floor squeaks in
my house!
Noise generation and control for
mechanical systems are described in
Chapters 13 and 14. The first chapter
reviews mechanical equipment, both
air handling and refrigeration devices,
in terms of its functions and noise
generation. Chapter 14 briefly reviews
sound attenua­tion in ducts, plenums,
sound attenuators and duct breakout and
break-in phenomena, concluding with a
• www.noisenewsinternational.net • www.i-ince.org
typical mechanical system noise
prediction calculation.
Chapters 15 and 16 provide an overview
of issues re­lating to acoustic design
for multi-family dwellings and office
buildings. Both chapters have an emphasis
on speech privacy and considerations
for mechanical equip­ment noise control.
Guidance is provided on sound iso­
lation and privacy expectations as related
to assembly construction and acoustic
performance ratings.
Design of rooms for speech is the topic
for Chapter 17. Issues include general
design criteria, sightline analysis to
maximize direct sound propagation, room
shaping, reverberation limits, comparison
of different speech intelligibility metrics
and applications to differ­ent room types.
An interesting feature is the section on
restaurant design. Many concepts in this
chapter are directly applicable to the
following chapters on mu­sic and multipurpose auditoria.
As an extension of Chapter 17, sound
reinforcement system design, is covered
in Chapter 18, starting with a review
of different loudspeaker types and
following with design concepts for system
electronics, loud­speaker directivity
parameters, and lastly, computer modeling
to include information on loudspeaker
coor­dinate geometry.
Chapter 19 covers design of concert and
opera halls. The chapter condenses much
of the work from the past 30 years with
emphasis on contributions by Barron,
Beranek and Bradley. The chapter
concludes with a sur­vey of significant
venues summarizing physical and acoustic
data for each.
Chapter 20 describes acoustic design for
multi­purpose auditoria, recital halls and
worship house sanctuaries to include
29
illustrative examples. The chapter
supplements material from earlier chapters
with diverse subjects such as stage shell,
pit and platform design, var­iable acoustics
(both passive and active), coupled
chambers and integrating sound
reinforcement systems.
The design of small rooms is reviewed in
Chapter 21. Topics include room modes,
effects of discrete sound reflections, lowfrequency sound control, loudspeaker
placement, diffusion and sound isolation
for recording, rehearsal and listening
rooms. The acoustic design for scoring
stages and Foley studios is a subject not
covered in other acoustics books.
The last chapter reviews acoustic
modeling, ray trac­ing and auralization
as means to predict and evaluate room
acoustic behavior. Information in this
chapter will be useful to help understand
commercial room acoustic programs that
are available.
In summary, the second edition of
Architectural Acoustics provides a
comprehensive overview to the many
aspects of architectural acoustics, sound
isola­tion, equipment noise control and
sound reinforcement systems, balancing
both theoretical and practical con­
siderations. A reader with no background
in acoustics will be able to understand the
topics because of intro­ductory material
presented before relevant chapters and
the author’s unambiguous writing style.
This book will serve as an excellent
textbook for a yearlong course for upper
level undergraduate or graduate students.
Practitioners will find much value in
the concise sum­maries contained in this
revised volume.

The Sound Book: The Science
of the Sonic Wonders of
the World

A reverberation time of 75 (seventy-five)
seconds? A cicada that can generate a
sound pressure level equal to that of a
pneumatic drill? You better believe it.
Follow­ing in the footsteps of Rodolphe
Radau and its 19th century Wonders of
Acoustics. Or the Phenomena of Sound,
Trevor Cox takes on the reader in an
incredible voyage around the world,
looking for (and discovering) the most
reverberant place on earth, playing an
organ constructed out of underground
caves and taking us to a concert where
the instruments are made of ice, to name
just a few stops along the journey. And
yes, we get to learn some fascinating
things about the animal kingdom and its
sounds, including that the African Cicada
can generate an SPL of 107 dB at 50
centimeters.
But this book goes far beyond putting
some interest­ing facts about sound
together. The author is able to ac­tually
bring the science of sound into a format
that is readily accessible to readers
without formal scientific training and still
remain satisfying to those who like to
approach the topics from a more rigorous
fashion. Rather than simply stating
results and findings, Trevor Cox actually
engages the reader into the discovery
pro­cess and even those with extensive
training in acoustics will actually have
no choice but to accept the reality that
there are a lot of things about sound
that one may not have known about; I
know this for a fact because that’s what
happened to me as I started to read this
won­derful book.
The clarity of the writing is outstanding;
Trevor Cox is always focused on
guiding the reader into that mo­ment
where “whoa” is the only appropriate
response to the discovery. He uses fun,
puns, self-deprecation, skepticism and
superb endnotes to create chapters that
read like mystery page-turners and leave
the reader ea­ger for the next stop on the
discovery voyage. This book should
be required reading for anyone who is
looking for amazement in everyday
life; it will turn readers into informed
listeners, and that by itself is a rather
impressive achievement. Highly
recommended.

Modelling and Managing Airport
Performance provides an integrated view
of state-of-the-art re­search on measuring
and improving the performance of airport
systems with consideration of both airside
and landside operations. The considered
facets of per­formance include capacity,
delays, economic costs, noise, emissions
and safety. Several of the contribu­tions
also examine policies for managing
congestion and allocating sparse capacity,
as well as for mitigat­ing the externalities
of noise, emissions, and safety/ risk. The
book is a compilation of articles devoted to
methodologies for analyzing, forecasting,
and improving the performance of airports
and air traffic flows with the following

Environmental Impact Analysis
wrestled with for decades, namely that
while aviation noise levels have decreased
significantly in absolute terms over the last
several decades, annoyance from
and resistance to airport operations
remains unchanged (or in some areas
is even increasing). The authors of
Chapter 6 review the effects of noise on
people, various policy approaches that
have been undertaken, and models for
predicting noise ex­posure from aircraft
operations.
Hansen et al. propose that better models
that address policy impacts, not simply
the impacts from the pollu­tants, should be
developed. These policy models would
allow for objective comparison of various
policy alterna­tives and would also allow
for evaluation of the impacts of multiple
pollutants (i.e., tradeoffs).
• Airport Safety Performance
In short, Chapter 6 proposes that better
models would enable comprehensive
policy analysis that would put the impact
and effects of noise in context with other
environmental pollutants and allow for
more effective decision-making.
• Scheduled Delay as an Indicator for
Airport Scheduling Performance
• Implementation of Airport Demand
Manage­ment Strategies: A European
Perspective
• Design and Justification for MarketBased Approaches to Airport
Congestion Manage­ment: The US
Experience, discussing slots, small
communities, and so forth.
I would recommend Chapter 6 of
Modelling and Managing Airport
Performance for those seeking a concise
summary of the range of environmental
chal­lenges facing airports.
Because this review is being published in
the Noise Control Engineering Journal, the
focus of this review will be on Chapter 6,
“New Methodologies for Airport
Environmental Impact Analysis,” by
Hansen, Ryerson, and Marchi, which
focuses on four key undesirable bypro­ducts
of airport and aviation operations: noise,
water runoff, air pollutants and Greenhouse
gas emissions (GHG).

Before I describe the contents of the
book, the bind­ing of this book is called
“perfect” but is similar to the binding of
cheap, paperback books. The pages are not
gathered and sewn into signatures. Instead
they are glued together with a thick layer of
glue. The paper is good but after extensive
use over a period of years, the book will
fall apart. This is unfortunate because this
is the kind of book that you might like to
keep on your shelf as a reference.
When I accepted the book to review,
I thought that it was a graduate level
textbook. However, there are no problems
at the end of each chapter. After I had
read a few different parts of the book,
I looked at the short biography of the
author. The author graduated with a
degree in an area of physics and then
entered the field of vibration engineering.
I have met others who fol­lowed the
same path and I am one of them. The
area of mechanical vibrations, as well
as acoustics, is based on analytical
mechanics, experimental mechanics, as
well the electrical engineering aspects
of data acquisi­tion and signal processing
and the more artistic area of the display of
quantitative information. Anyone working
in this field is bound to interact with
people who use the particular vocabulary
of physics, mathe­matics, mechanical or
electrical engineering. I think this book
successfully addresses that problem in a
fairly systematic way.
The book consists of roughly four parts:
a prelimi­nary introduction (pp. 1–118),
SDOF, MDOF and con­tinuous vibration
systems (pp. 119–420), experimental
modal analysis (pp. 421–476) and random
vibrations (pp. 477–584). There are also
two appendices: vector and matrix algebra
and assessment of vibration intensity.
There are 117 references, among which
I recognized several helpful texts and
handbooks.
31
The preliminary introduction includes
some funda­mentals like linearity, what
degrees of freedom means, complex
notation, beat phenomena, physical
descrip­tion of motion (displacement,
velocity and accelera­tion), idealized
mechanical components (mass, spring and
dashpot), and analytical mechanics. These
funda­mental discussions show clearly to
an electrical engi­neer the definitions of
mechanical components that are analogs of
inductors, capacitors and resistors. There
is an introduction to Fourier series and
trans­forms that includes some sophisticated
concepts and places them in the field of
mechanical vibrations.
The chapter on analytical mechanics is
thorough and includes Hamiltonian and
Lagrangian methods. In some chapters
“bra-ket” notation is used while in others,
inte­gral and differential notation.
The part on vibrational systems includes
a chapter on SDOF systems: the effects
of damping and definitions of quantitative
descriptions, such as damping ratio,
log­arithmic decrement, displacement
velocity and acceler­ation resonant
frequencies, the effects of damping and
equivalent viscous damping, frequency
response, shock response and transient
response. Approximate methods for
estimating the response of a system that
is approximated as an SDOF are given,
too. The chapter on MDOF contains
several cases of increasing complexity
before presenting matrix formalism and
increasingly more complicated conditions
such as proportional and non-proportional
damping and the response to excita­
tion. The chapter on continuous systems
presents the solutions to several wellknown problems: the string, membranes,
thin rods and thin circular and rectangular
plates. The chapter on MDOF and
continuous systems includes the modal
approach and the approximate
32
Rayleigh–Ritz method. Numerical
examples are given sometimes.
The third part on experimental modal
analysis is only one chapter, which used
to be three chapters according to the
preface to the second edition. In spite
of this, I found the chapter to be clearly
written and introduced me, who has never
performed experimental modal anal­ysis,
to the subject. The chapter includes three
primary questions to be answered before
any experiment is per­formed: “What do
we need to know,” “What is the de­sired
outcome,” and “After the experiment, what
steps are taken and why?” The two main
purposes of performing modal analysis
are to determine the levels of response of
a specific structure or to validate a model
of the structure. The chapter does not
include electrical issues around recording
the data, but does include me­chanical
considerations, such as the mass of an
acceler­ometer and the mounting of the
structure. Specific examples of Bode and
Nyquist plots of the receptance, mobility
and accelerance are shown with clear
explana­tions of the behavior. While reading
about the utility of log–log plots,
I remembered being told by a colleague
that long ago, one goal of applied scientists
was the cre­ation of graph paper that
presented any data as a straight line.
The chapter does not present specifics
about a list of 25 popular methods of
parameter estima­tion but a comprehensive
reference is given. From the preliminary
information given in the chapter, I felt
con­fident that I could learn any of
the methods.
The fourth part consists of two chapters
on probabil­ity, statistics, stochastic
processes and random vibra­tions. Basic
definitions, a few specific distributions,
marginal distributions and random vectors
are included, some with more detail
than others. There are several references
given for a deeper discussion of any
topic. The last chapter presents material
on stochastic pro­cesses. I wish that the
author had included a longer dis­cussion
of practical considerations of stationarity
and ergodicity because these tend to
be confusing to many people and data
can be taken and analyzed improperly.
However, the chapter does describe the
properties, in­cluding bandwidth, of power
spectral densities and the steady-state
and transient responses of systems to
stationary vibrations. Threshold crossing
rate, peak distri­bution and fatigue damage
from random excitation are presented for
narrowband random vibrations.
In summary, I found the book to be well
written with clear explanations. I found
only two typographical errors and I could
easily work around them. I think that this
book is a good reference book to have on
the shelf to refresh your memory about
some aspects of vibrations or to find a
reference to deepen your understanding.
It is also a good book for people – like
physicists or electrical engineers – who
have a technical background but not in
this area of mechanical engineering. In
my opinion, there are two deficiencies in
this book. First, the book could be more
useful if numerical recipes and numerical
examples were included in more sections.
Solved nu­merical examples can be useful
for developing and using software.
Second, a list of all symbols would also
be helpful. However, the bottom line is
that I am happy that I was given this book
to review; I will keep it on my shelf and
use it as a handy reference with clearly
written ver­bal, mathematical and graphical
descriptions.

Underwater Acoustic
Modeling and Simulation,
Fourth Edition
have been made with each edition and the
fourth edition is no exception.
Paul C. Etter
CRC Press, Boca Raton, FL, (2013),
554 pp, hardbound, 215.96 USD,
ISBN: 978-1-4665-6493-0
As with the prior editions, Etter’s fourth
edition text is ideally suited for use by
professional and student acousticians,
acoustical oceanographers, applied
mathematicians, sonar technologists and
operations analysts and system engineers.
The author assumes that the reader
already has a basic technical foundation in
underwater acoustics and the text therefore
concentrates primarily on covering
the wide-ranging variety of modeling
approaches applicable to this area.
The 2013 fourth edition of Paul C. Etter’s
text entitled Underwater Acoustic Modeling
and Simulation deals predominantly
with physical and/or empirical modeling
methods and approaches for predicting a
variety of underwater acoustic phenomena
including acoustic propagation, noise
and reverberation occurring in the ocean
environment. Practical information on
the application of these models to sonar
operation and performance and also the
implementation of models over time
(termed “simulation” by the author and
introduced to the title and the text back
in the third edition) are discussed in later
chapters. New topics specifically added in
the fourth edition include the impact on
underwater acoustic modeling tools of a
variety of more recent undersea subjects
including marine mammal protection,
the impact of increasing ocean
acidification, undersea noise pollution,
effects of climate change, marine wind
farm development, etc.
Etter’s evolution from the first edition of
this book (entitled Underwater Acoustic
Modeling and published in 1991) to the
present fourth edition has occurred over
a period of nearly four decades. Overall,
looking back on the changes made to the
book during that period with each new
edition, it has been a fine progression.
Real-world changes to the technical interest
areas and priorities relating to underwater
acoustics modeling (e.g., the shift in
emphasis to acoustic prediction in shallowrather than deep-water environments) have
successfully been incorporated into later
editions over the years. Relatively weighty
improvements and updates to the material
2014 September www.inceusa.org
While the text is fairly detailed and
extensive, this reviewer believes that it is
intended primarily as an introductory or
illustrative examination of a broad field of
underwater acoustic modeling methods. As
such, it is likely aimed more at graduate
students and professionals interested
in learning about the full spectrum of
underwater acoustics modeling and
simulation methods or classes of models
rather than for practitioners requiring more
focused and in-depth information into any
one particular model or numerical code.
book, has clearly been extensively
updated with regard to recent work and
developments in the literature. Following
an updating of developments in both
modeling and simulation since the third
edition, Chapter 1 also contains a short
treatment of recent real-world operational
challenges in the areas of naval operations
(e.g., Unmanned Underwater Vehicles
(UUV’s)), the offshore commercial sector
(e.g., marine-based oil exploration) and
general oceanography research.
Chapter 2 contains a good summary or
review of a variety of phenomena related
to basic acoustical oceanography including
ocean fluid properties, their relation to
sound speed and propagation direction
determination, the effect of sea surface
and bottom boundaries, dynamic features
including wind and ocean currents and
internal waves and finally the impact on
sound of biologics.
Starting from his first edition and carrying
through to this latest 2013 edition, one
of Etter’s chief stated goals is to provide
the reader with precise information on
both the underlying assumptions behind
each modeling type or method as well
as describing its domain or limits of
applicability. The author has been very
successful in this goal, since virtually
every modeling approach considered is
accompanied by useful information on
its specific uses, selection guidelines,
shortcomings and restrictions.
Most of the “meat” of the text’s coverage
of underwater acoustics modeling is
contained in Chapters 3–10 which
together cover broad classes of modeling
approaches in the important acoustical
areas of propagation (Chapters 3–5), noise
(Chapters 7–8), and reverberation (Chapters
9–10). In each of these three areas, the text
treatment of the topic includes chapters on
both the physical and then the mathematical
modeling of these phenomena. Chapter 6,
a new chapter added in the fourth edition,
covers a wide variety of specialized
modern topics and applications related to
propagation including broadband modeling,
nonlinear acoustics, underwater acoustic
networks and vehicles, time-reversal
techniques and marine mammal protection
modeling efforts.
The text begins with an introductory
chapter offering an excellent overview of
the current state of underwater acoustics
modeling and simulation. This chapter,
as with the remainder of this new edition
Chapter 11 shifts concentration from
the underwater acoustics modeling of
propagation, noise and reverberation
covered in the earlier chapters towards a
more applied examination of the use of
• www.noisenewsinternational.net • www.i-ince.org
33
these aforementioned models in the field
of sonar system performance. However,
unlike other navy sonar texts which delve
heavily into specific sonar array designs
and operation, Etter’s treatment of the topic
continues to place emphasis on modeling
the underwater acoustic and oceanographic
environment itself and how that relates
to general sonar system performance
and objectives.
The seemingly straightforward process
of model evaluation is discussed from
a variety of real-world perspectives in
Chapter 12, which also contains a historical
account of a number of larger-scale
evaluation efforts sponsored by the US
Navy and others. Finally, as mentioned,
Chapter 13 is devoted solely to issues
related to simulation, defined by Etter as
the implementation of models over time.
The brief coverage of simulation follows
as a natural and logical extension from the
detailed modeling concepts discussed in
the earlier chapters.
One of the unique strengths of Etter’s book
is how comprehensively referenced it is
throughout. Following the last chapter is
a very impressive list of references, each
individually cited in the book for a definite
purpose. In addition to the reference
citations included within the body of the
text, an Author Index is included after the
Subject index which is also convenient.
Furthermore, unlike a recent trend with
some other authors of later edition texts
to just “tweak” the earlier edition and
correct minor errata, it is clear that Etter
has taken the time with this latest edition to
reinvestigate the literature in each chapter’s
topic and included additional upto-date
information and references.
Finally, a newly added Appendix D to the
fourth edition includes Problem Sets for
each chapter. This has likely been added
in an attempt to allow use of the text in a
graduate-level course setting. While the
34
number of problems included for each
chapter is so far very small, it is a good
start on a useful and welcome addition to
the book.
Overall, Paul C. Etter’s 2013 fourth
edition of Underwater Acoustic Modeling
and Simulation is an excellent and
comprehensive introduction to an
extremely broad spectrum of modeling
methods and approaches in underwater
acoustics and oceanography. While earlier
editions of this text were already widely
recognized as noteworthy and authoritative
in the field, useful and meaningful updates
and improvements have been made in
this current edition and it is a highly
recommended read.

Acoustics of Small Rooms
Mendel Kleiner and Jiri Tichy
CRC Press, Taylor & Francis Group,
Boca Raton, Florida, (2010), 491 pp.,
hardbound, 120.00 USD,
ISBN 9780415779302
The acoustics of small rooms has been
of interest since the dawn of recording
in the late 19th century. It became a field
for study for about 100 years ago after
the development of broadcast radio and
concerted re­search in the 1930s. Some
seminal papers by Morse and Bolt (Rev
Modern Physics, v16, 1944) and Bolt
(JASA, v18, 1946) appeared after World
War II and many thereafter. The term “size
matters” is one that is true in acoustics, and
small rooms have, when wave­lengths are
similar to, and greater than the dimensions
of a room simple geometric and statistical
analysis breaks down.
Mendel Kleiner and Jiri Tichy, Professors
Emeritus at Chalmers University of
Technology and The Penn­sylvania State
University, respectively, in Acoustics of
Small Rooms have produced a useful and
up-to-date guide for serious students and
practitioners of small room design, as well
as the end-users of such rooms.
There are many texts that address room
acoustics, but these focus, and have an
emphasis, on the acoustics of larger
rooms, such as concert halls, opera houses,
auditoriums and the like, and there are
many texts that deal with perceptual
acoustics (psychoacoustics). The concise
and logical layout in Acoustics of Small
Rooms allows the reader to access
the information in these many tests in
one place and this book presents the
mathematical physics, material analysis,
human factors and audio engineering, and
computer and measurement techniques
necessary for understanding sound fields
and their perception in small rooms.
The physics of small room sound fields
is presented first in a chapter of the same
name. In addition to the usual derivation
of the wave equation for free waves and
a review of acoustic metrics and analysis
techni­ques, the authors derive the wave
equation for forced waves — necessary for
small rooms in which sound systems are
utilized. This chapter, and others, assumes
a working knowledge of calculus including
complex operators.
Next, the authors look at the sound fields
in enclo­sures. Wall impedance and the
boundary conditions this imposes on the
eigen-function solution to wave equa­
tion are key to the development of modal
density, modes and forced waves. In
addition, the statistical parameters of the
room, such as reverberation, are presented.
In the chapter titled “Geometrical
Acoustics”, the authors discuss transient
(impulse) sounds that are produced by
many sources and the hearing system’s
www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014
September
response to these sounds, ray tracing,
diffraction, sur­face dimensions, Fresnel
zones and the response (build-up and
decay) of real rooms to impulses.
A key design element in many rooms is
absorption and the mechanisms for wall
treatments which are covered next. The
discussion for porous, resonators and
complex absorbers is detailed with both
the equations that describe the physical
performance of the devices, along with
many illustrations. As with some of
the chap­ters in the text, the analysis is
rigorous. Another impor­tant element
in room design in general, and at times
overlooked in small rooms, is diffusion of
the sound field by the room boundaries —
which when used correctly can be an
important part of the room design. The
chapter titled “Diffusion” presents a
review of the basic princi­ples of diffusors,
techniques for the measurement of
scattering and diffusion, design of these
elements (in­cluding the effect of fins), and
the absorption character­istics of diffusors.
With the basics presented in the previous
chapters, the next three chapters, The Ear,
Psychoacoustics, and Spatial Hearing,
give the reader an excellent introduc­tion to
how humans hear and how they perceive
what we hear. Sometimes this aspect is
overlooked in the design process.
The tougher parts of small room design are
covered in the next chapters. The chapter
on rooms with sound systems looks at how
the sound field can be analyzed in two
parts to better understand the interaction
between the room (which is basically
2014 September www.inceusa.org
a filter) and the loudspea­kers. For low
frequencies loudspeaker placement and
mode damping are important. For the
mid-and high frequencies reflections,
reverberation, absorption and diffusion are
important.
The text next takes a more detailed look at
low-frequency sound field optimization and
the difficulties in achieving same — modes,
modal density and modal overlap – and two
useful implementation techniques – wave
modification and room geometry.
Now, over the years that sound equipment
and room acoustics for sound reproduction
have been studied, some general
characteristics for successful design have
been codified. ITU-R BS.1116-1 and IEC
268-13 are two of the more common ones
which specify symmetry (for stereophonic
use) and the reduction of strong reflections.
The near anechoic, live-end-dead-end,
reflection free zone, and controlled image
design protocol for control rooms are
reviewed as well as suggestions for
home systems.
The final chapters are devoted to small
room de­sign for voice and music
practice, modeling of room acoustics and
measurements. For voice and music practice
rooms, the design factors include the effect
of instrument sound power in a small
space and the risk of hearing impairment,
background noise levels, similarity between
the rehearsal space and the perfor­mance
space, reverberation time, geometry
and diffu­sion, and the problems when
remodeling an existing space or spaces.
• www.noisenewsinternational.net • www.i-ince.org
The chapter on modeling discusses
some physical and computer modeling
techniques, and since the three models –
geometrical, statistical, and wave
mechanical – each cannot span the full
frequency range, so espe­cially for small
rooms, the frequency range of interest is
split into low and high frequency parts.
The pros and cons of physical (scale),
numerical models (BEM, FEM), and
auralization are reviewed.
The last chapter takes a look at
measurement — an essential part of
acoustic engineering, or as Lord Kelvin
said “To measure is to know” and “If
you cannot measure it, you can not
improve it.” Acoustic metrics such as
sound pressure, particle velocity, sound
intensity measurement using a microphone
or microphones, measurement sources
such as loudspeakers, some of the
derived metrics (distortion and noises),
uncertainty (yes — there is uncertainty in
audio measurements), filters, weightings,
transducer noise, measurement below
the Schroeder frequency, and more are
discussed in this clear and concise chapter.
Each chapter has a list of the references
noted in the text and shows the depth of
research by the authors. Acoustics of Small
Rooms is a useful reference, tutorial and
guide for the designer, builder and end-user
of small rooms.

INCE/USA is a sponsor of the upcoming
documentary film, In Pursuit of Silence.
The movie could reach over two million
people through film festivals, theatrical
releases, television broadcasts and digital
release. INCE/USA chose to support the
film based on the potential for reaching far
outside of our organization to those who
possibly haven’t considered the effects
of noise and the potential to improve
noisy environments. While noise control
engineering won’t be a focus of the film,
38
we fully expect it to be discussed in the
movie in some capacity, particularly since
INCE/USA has the privilege of direct input
through our support.
Additionally, INCE/USA will be receiving
two short public-service videos that will
be released as part of the special features
on any DVD release. The public service
topics chosen are relevant to noise control
engineering and its effects on quality of life
and product noise control ratings. We are
working with the filmmakers to make these
topics as engaging to the general public as
possible.

Sensidyne: What’s Shaking up
the American Workforce?
Nationally, almost 60 percent of all workrelated illnesses are musculoskeletal
disorders (MSDs). One in 10 of these are
vibration related. In the United States
alone, 2.5 million workers are exposed
daily to hand-arm vibration from power
tools they use on their job.
These numbers are shocking! In the
U.S. alone about 2.5 million workers are
40
exposed daily to Hand-Arm Vibration
[HAV] from the power tools they use on
their jobs. Whole Body Vibration [WBV]
exposured are equally as concerning.
Risks and effects of vibration on the
human body in the form of whole body
vibration and hand-arm vibration are well
documented, and yet this is one area of
occupational health and safety that many
overlook.
It is time for a progressive, proactive,
and responsible approach to educating
workers and supervisors to the the
dangers of HAV and WBV and the
methods of identifying, measuring, and
protecting workers from unnecessary
exposure.

New NIOSH Website on Buy Quiet
Noise-induced hearing loss is the most
common work-related injury in the United
States. Each year approximately 22 million
U.S. workers are exposed to noise loud
enough to damage their hearing. To create
a more healthful workplace, the National
Institute for Occupational Safety and
Health (NIOSH) recommends preventing
hazardous noise through controls for
noise exposure and encourages business
owners to create Buy Quiet programs as a
first step. For more information go to http://
www.cdc.gov/niosh/topics/buyquiet/.
VAUC 2014
The event will showcase presentations
on various topics such as windnoise
for automotive and high-speed train

Preamplifier for Acoustic
Testing for Space Constrained
Applications
PCB Piezotronics introduces a new
short preamplifier for test engineers
and acoustic consultants taking
measurements in spaces where traditional
microphone systems won’t fit or where
space constraints are a concern. This new preamplifier, Model 426A07,
converts a high impedance signal from
a measurement microphone into a low
impedance signal. The preamplifier can
be paired with any PCB® ¼" free-field,
random incidence (diffuse field) and
pressure microphone cartridges to test
high frequencies ranging from the human
audible range (20 Hz to 20 kHz) up to
ultrasonic frequencies (greater than 100
kHz) and high amplitude measurements past
the human threshold of pain (up to 194 dB).

ZweigWhite Unveils New
Corporate Name and Logo
ZweigWhite has introduced a new
corporate name and logo that reinforces
its commitment to growth through an
investment in new products and services
as well as delivery methods.
The company has changed its name to the
Zweig Group and developed a new logo
that reflects its evolution as a company
while offering a modern appeal.
“We are bringing the mission that we were
founded on into sharp focus along with a
renewed commitment take this company
www.inceusa.org • www.noisenewsinternational.net • www.i-ince.org 2014
September
to the next level,” said Chad Clinehens,
Zweig Group Executive Vice President. “It
is important that our new name and new
logo preserve those equities we built over
the past 25 years, while communicating
we are changing and evolving with the
times and that we will be exactly what our
clients need us to be. Going forward, we
are going to look and feel different.”
The Zweig Group’s new logo utilizes a
square shape to reinforce stability and
represent a uniform building block. The
“Z” is made with a designer’s scale and
triangle, common drafting tools used by
architect and engineers. The red color
is brought back from the first logo the
company used when it was founded as
Mark Zweig and Associates in 1988.
“Our new logo is a great blend of the past
and the future,” said Mark Zweig, Zweig
Group CEO and Founder. “This company has
gone through a lot over the past 25 years
but we have stayed true to our mission.
That important mission is empowering firms
in the architecture, engineering, planning
and environmental industry and the people
that work in them to be more successful.”
The re-branding campaign was launched
at the firm’s annual Hot Firm and A/E
Industry Awards Conference that was
held in Beverly Hills last week. The
announcement kicked off a complete
re-branding that included the launch of a
new website at www.zweiggroup.com.

The Zweig Group welcomes
Randy Wilburn to the Executive
Search team.
Now Available:
AMERICAN NATIONAL
STANDARD
ZweigWhite is excited to announce
that Randy Wilburn is re-joining the
firm to help grow the executive search
division. Wilburn, who first worked for the
Zweig Ghite in the firm’s executive search
team in the 1990s/2000s, was an owner in
the firm. Randy left the firm when it was
sold in 2004 to a private equity group.
Now that the Zweig Group is back in the
hands of the original founding partner,
Mark Zweig, Randy is re-joining the firm
to help them build a key part of their
business.
Electroacoustics—Octave-band and
Fractional-octaveband Filters—Part 1:
Specifications (a Nationally Adopted
International Standard)
SoundPLAN #11 Released
This standard provides performance
requirements for analog, sampled-data,
and digital implementations of bandpass filters that comprise a filter set
or spectrum analyzer for acoustical
measurements. It supersedes ANSI/ASA
S1.11-2004 (R2009) American National
Standard Specification for Octave-Band
and Fractional-Octave-Band Analog
and Digital Filters, and is an identical
national adoption of IEC 61260:2014
Electroacoustics – Octave-band and
fractional-octave-band filters, Part 1:
Specifications. Significant changes from
previous versions is that IEC 61260 has
been adopted in full: (1) the original test
methods of IEC 61260 clause 5 that was
moved to an informative annex was
replaced as normative, (2) the term “band
number,” was replaced, and (3) some
references were removed. This standard
replaces ANSI/ASA S1.11-2004 (R 2009).

“It’s pretty exciting for me to come back
to the Zweig Group and the management
consulting and executive search field.
I can take what I’ve learned over
the past decade and apply it into the
AEC framework,” said Wilburn. “I am
looking forward to again being a part of
what I have always viewed as a great
organization.” www.zweiggroup.com
