Transcript NOISE AS A CONSTRAINING FACTOR IN 21ST CENTURY …

THE GLOBAL NOISE ISSUE
Report from the
CAETS Noise Study Committee
CAETS 2009 Calgary
Tor Kihlman, IVA, Chair
(presented by Bill Lang, NAE, Secretary)

BACKGROUND
At CAETS 2007 Tokyo the Council accepted
an IVA proposal:
• to assess the global noise issue as a
constraining factor in 21st Century
urbanization and the technology available to
address this problem, and
• to consider the broad subject of noise with
initial consideration of European
transportation noise sources.
www.iva.se
OBJECTIVE: A Technology
Assessment
• What noise control technology is available
today and to what extent has it been
implemented in today’s products?
• What new noise control technology needs to
be developed and how is it progressing?
• How can noise control technologists
promote the implementation of available and
future technology?

FIRST CAETS WORKSHOP
• A CAETS workshop, organized by individual
members of nine CAETS academies, was
held at the Institute of Sound and Vibration
Research (ISVR) of the University of
Southampton, UK, on June 2 through 4, 2008.
• Title of the workshop: “The design of lownoise vehicles for air, road, and rail
transportation.”

FINDINGS TO DATE
1. Vehicle noise emissions (air, road, and rail)
are a global issue and are the predominant
sources of community noise. Control at the
source is the most effective way to deal with
them.
2. Air-vehicle technology is already globalised
due to international cooperation among
engineers, manufacturers, and governmental
organizations.
www.iva.se
FINDINGS continued
3. Road-vehicle technology is partially globalized
by the manufacturers, regulators, and the
worldwide market.
4. Advanced rail-vehicle and track technology is
well-developed but primarily European and
Asian.
www.iva.se
FINDINGS continued
5. Vehicle-generated noise, while extremely
important, is only part of the global noise
issue that also includes occupational noise
and the noise generated by industrial
equipment and consumer products.

APPROVED ACTION
At CAETS 2008 Den Haag the Council
accepted an IVA proposal that:
• The study of noise control technology be
extended from the European to the global
scene, and
• Noise at the workplace and noise produced
by industrial equipment and consumer
products be included in the study.

FORUM IN OTTAWA
• A forum organized by the CAETS Noise
Study Committee will be held in Ottawa,
Canada, on August 24-26, 2009.
• The title of the forum is “Second CAETS
forum on worldwide noise sources.”

ISSUES FOR COPENHAGEN
At CAETS 2010 Copenhagen the Noise Study
Committee will report on:
• The role of technology in providing control of
the dominant noise sources in our global
society.
• How to communicate those conclusions on
available and future technology to the public
and to policymakers.
www.iva.se
TECHNICAL SUPPORT
FOR STUDY
The International Institute of Noise Control
Engineering (I-INCE) is currently working on a
report on technical issues related to global
policies for the control of noise source emissions.
This study is being undertaken to support the
work of the CAETS Noise Study Committee.
