Sources & Propagation
This committee brings together INCE members with interests related to noise sources and how that noise propagates to the listener. Regarding noise sources the committee promotes characterizing noise sources, understanding their radiation mechanisms, and devising noise control methodologies via source modification. Regarding propagation the committee seeks improved methods for measuring and predicting the propagation of noise through both structures and the air. Source alteration techniques, outdoor and indoor sound propagation, and scattering and diffraction are all within the purview of the sources and propagation technical committee. The committee is committed both to developing new understanding of how the sound from real noise sources is generated and gets to the listener and to applying engineering principles to minimize the noise.
Passive Noise Control
Chair: J. Stuart Bolton
The objective of the committee is to promote activities and disseminate information in passive control of noise and vibration. Areas of interest include, but are not confined to, analytical, computational, and experimental efforts on: (1) reactive, dissipative, and hybrid mufflers and silencers; (2) flow noise and suppression; (3) flow-acoustic coupling and suppression; (4) flow-structure interaction; and (5) acoustical materials used for sound absorption, damping, vibration isolation, structures, and sound barriers. The foregoing objective is achieved by: (1) organizing technical sessions at the NOISE-CON Conference and INTER-NOISE Congress and Exposition, thereby creating an effective exchange environment between research and application communities; and (2) encouraging participants to publish their works in the Noise Control Engineering Journal. Current activity is organization of sessions for INTER-NOISE 2011 with Kimihiro Sakagami and Masahiro Toyoda.
The purpose of the Active Control Technical Committee is to foster research, applications, unified practice and communication of new techniques in the active control of sound and vibration. Areas of interest to the committee include not only applications involving noise and vibration control, but also sound field reconstruction and other novel applications of active control. Subtopics of interest include physical principles of active control, algorithms, transducers, sensing and actuating techniques, and hardware design. To accomplish these objectives, the Committee seeks to do the following: (1) organize sessions for NOISE-CON and INTER-NOISE meetings; (2) provide continued support for the ACTIVE symposia which have been held on a regular basis; (3) encourage members and others to publish active control research and case histories in the Noise Control Engineering Journal; and (4) provide a forum for information exchange as a means of promoting research and unified practice in the field.
Perception and Effects of Noise
Chair: Wade Bray
This group has focused on organizing sessions for conferences and one-day symposia (SQS98 and SQS 2002) associated with INCE and international INCE meetings. Topics of interest include:
- Sound quality modeling: metrics, psychoacoustic testing, standardization
- Binaural sound quality
- Sound quality of environmental sounds
- Designing the sound of products
- Influence of attributes other than loudness on sound quality
- Human response to vibration and coupling of response to noise and vibration
- Modeling and predicting annoyance including the influence of information and context on response modeling
- Surveying and psychoacoustic testing techniques
Experimental Techniques and Instrumentation
The committee acts as a forum for the dissemination of information and research results on experimental and instrumentation methods in the fields of noise and vibration control, and acoustics. This forum is established through periodic meetings at NOISE-CON and INTER-NOISE conferences, sessions organized at these conferences, and the organization of seminars or short courses in conjunction with these same conferences. From these conferences, the committee will work with the Noise Control Engineering Journal Board to identify papers of special merit for inclusion in the Journal. In addition, the committee strives to provide an interface to international and national groups on relevant experimental and measurement procedures, facilitate the coalition of divergent approaches to the same experimental and measurement problems, and act as a resource for those seeking information on current experimental and instrumentation developments.
The Transportation Noise Technical Committee will provide forums for the exchange of technical and regulatory information related to the development and application of noise and vibration research, and methodologies to the transportation industry. A major thrust of the technical exchanges will be the integration and dissemination of applied research results into the industrial community. Technical topics will cover noise and vibration tests, analysis and processes that are related to surface and air transportation noise concerns from customer and regulatory perspectives. Current activity is the organization of Noise-Con 2011 that will be jointly sponsored by the Transportation Research Board (TRB) Committee on Transportation-Related Noise and Vibration.
The primary focus of the Industrial Noise Control Committee is to exchange technical information on the methods to reduce noise and vibration of industrial machinery. Industrial machinery by definition is portable and stationary machinery that is 100 horsepower or greater. Examples of industrial machinery include farming equipment, highway construction portable equipment, mining equipment, compressors, centrifugal pumps, pneumatic and hydraulic pumps, rock drilling equipment, portable power generators, oil refinery machinery, and manufacturing machinery. The committee provides a forum for exchange of technical information related to the management of machinery noise and vibration. Areas of interest to the Committee include new product development, manufacturing, and fielding issues. In particular, the Committee seeks to do the following: (1) organize sessions for NOISE-CON and INTER-NOISE meetings; (2) sponsor specialized workshops and seminars in conjunction with NOISE-CON conferences or INTER-NOISE congresses; (3) encourage INCE members and others to publish, in Noise News International and the Noise Control Engineering Journal, case histories as well as accounts of successful programs and approaches related to the management of industrial noise; (4) serve as an information exchange and clearinghouse for members and others interested in the management of industrial noise; (5) form alliances with other professional and trade organizations whose charters overlap or complement those of the Committee; (5) develop, provide, and/or advertise the availability of educational materials for members and others to use in their outreach and guidance programs.
Chair: Larry Finegold
Committee members: Frank Brittain, Bennett Brooks, Ken Kaliski
The Technical Committee on Community Noise (TCCN) was formed for the purpose of promoting the use of noise control engineering technologies and adequate noise management policies to reduce noise exposure in communities across America to levels necessary to adequately protect the health and welfare of the US population. To fulfill these objectives, INCE TCCN will pursue the following general priorities:
- Promote the development and use of state-of-the-art noise control technologies, including providing information on these technologies to the public and relevant government agencies
- Promote sponsorship and conduct of high priority research on the effects of noise, including health effects, community annoyance and sleep disturbance research
- Support the development of up-to-date national and local government noise management and land use policies, including increased cooperation between industry, government and the public on noise control issues
- Support programs to educate the public on the adverse effects of community and environmental noise exposure
- Support the continued professional development of the noise control engineering field and promotion of their services to communities
- Coordinate INCE/USA community noise activities with those of other national and international professional acoustics organizations and government agencies
Product Noise Emissions
Chair: Matt Nobile
The scope of the Product Noise Emissions Technical Committee is noise emission from products in general, without focusing on a specific product type or family. The committee will primarily be concerned with the fundamental aspects of acoustical measurement technology, methodology, and standardization as they are applied to products in general. The scope also includes methods for disseminating information on product noise emissions to consumers and the general public, such as product noise declarations and labels. Noise control topics may be considered when appropriate, but these are usually better placed under the Passive Control and Active Control Technical Committees. Similarly, the perceptual aspects of product noise emissions are not included in this scope since these are addressed in the Perception and Effects of Noise TC. One of the goals of this committee is to spin off sub-committees dealing with particular product families that will address noise emission issues specific to that family and that will develop measurement and declaration test codes specific to their industries. The Sub-Committee on ITE is an example of this (even though it has existed as a separate TC long before the establishment of this parent TC). Products include small and large household appliances, information technology products, home entertainment products, power tools, lawn and garden equipment, air-conditioning products, medical equipment, test instrumentation, and many others. Transport vehicles, outdoor construction equipment, and typically large industrial equipment are not included in the scope of this committee.
Current activity includes development of a new scheme for rating the noise emission levels of products for the general public.
Sub-Committee on Information Technology Equipment (ITE)
Chair: Jeff Schmitt
The scope of the Information Technology Equipment Technical Sub-Committee is noise control engineering relating to information technology equipment (ITE), with a primary focus on acoustical measurement technology, methodology, and standardization. In addition to organizing special sessions at INCE conferences and soliciting technical papers for NCEJ, the principal activities of the Committee are to monitor, elucidate, and continually reevaluate the technical underpinnings of the acoustical standards and test codes pertinent to the ITE industry. Given that our members are volunteers with limited time and resources, the activities undertaken by the committee should meet the following practical criteria: (i) can be reasonably handled by the resources available; (ii) are directly related to the mission of the TC/ITE; (iii) are important to the IT industry as a whole; (iv) are timely, in terms of work being done by other committees allied to the IT industry (such as standards writing groups); (v) are of strong interest to a majority of the TC members or potential TC members; (vi) are within the realm of expertise of the TC members or potential TC members; and (vii) are of a nonproprietary nature to allow competing firms to cooperate freely. The results of TC/ITE activities should benefit either INCE members in general or members of working groups developing standards and test codes for the ITE industry.
Current activity includes review and update of IT noise emissions standards including ECMA-74, ISO 7779, ANSI S12.10 and others. Development of new methods for measurement and evaluation of tones.
Prediction and Modeling Techniques
This committee will provide a forum for the dissemination and clarification of information related to the direct application of large scale computer analysis codes or software to noise control and acoustic problems. Analysis methods or codes of interest include finite and boundary element methods, statistical energy analysis, ray tracing, transfer matrix and other computational techniques for addressing interior and exterior sound propagation and radiation issues including interactions with vibrating structures and other media. An attempt will be made to establish a clear forum on the applicability of existing or new codes and numerical techniques to contemporary noise control problems in industry or society. To facilitate this important task, the committee will organize special technical sessions for NOISE-CON and INTER-NOISE meetings, solicit authoritative papers for Noise Control Engineering Journal, and provide a forum for its members in maintaining and developing the science and art of computer modeling. Other activities may include the formulation of benchmark noise control problems for analysis verification, organizing round robin modeling exercises, and liaison with other technical committees or professional societies.
The objective of the Building Acoustics Technical Committee is to advance the understanding of acoustical performance of building components, materials, and systems, with the ultimate goal of improving the acoustical quality for buildings of all types. This is done by organizing technical sessions at INCE conferences, encouraging the publication of papers on related topics, and disseminating relevant information to the Noise Control Engineering community, American Institute of Architects, American Society of Heating, Refrigeration, and Air Conditioning Engineers, other professional groups, and the public. Primary topics include criteria for sound quality in buildings, acoustical performance of building materials including standard construction materials as well as special acoustical products, prediction of sound levels in buildings, sound propagation through building structures and sound produced by HVAC, electrical and plumbing systems.
The committee seeks to identify building noise control topics of interest to the building development, design, and owner sectors through two means: 1) the consulting practice of acoustical consultants on the committee and 2) standards activities in the building acoustics areas. Once identified, NOISE-CON and INTER-NOISE sessions would be developed that address these areas of interest. Persons who are working in these areas and known by committee members would be invited to give papers at these sessions. These would be individuals known to committee members directly or indirectly through contacts with other members. The invited papers would form the basis of a session to which a general solicitation of papers would be made. The next, and most critical step, is to encourage presenters to prepare manuscripts for submission to NCEJ for consideration for publication.
Chair: Richard Peppin
This technical activity represents the technical interests of INCE as it applies to national and international consensus standards in acoustics and vibrations. One major activity is to mobilize people to assist in organizing sessions, developing special topics for NCEJ, and keeping INCE BOD and the members informed about the committee activities through the VP of Technical Activities.
Additionally, with INCE as a voting member in the American National Standards Institute (ANSI) Committee S12 on Noise, (The Acoustical Society of America (ASA) provides the Secretariat for the committee) the Chair of this technical activity, represents INCE on that committee. S12 is the committee responsible for the development of standards, specifications, and terminology in the field of acoustical noise pertaining to methods of measurement, evaluation, and control of as related to the areas of environmental and occupational noise. This Committee of INCE acts as the liaison between INCE members and ASA S12.
This newly formed technical committee is focused on the vibration of structures leading to noise generation in buildings and communities and includes prediction and measurement of ground borne vibration from ground transportation systems, rattle and vibration induced by aircraft, and design of structures and construction methodologies to mittigate transmission of vibration and subsequent noise generation.
