Active and Passive Noise Control Committee

Objectives and Focus of the Commitee
The objective of the Active and Passive Noise Control Committee is to increase and disseminate theoretical and practical methodologies aimed at reducing noise.  All aspects of the noise control process are of interest, from noise source identification techniques to final installation and placement procedures of treatments.  The topics of focus for the committee are active, passive, and hybrid approaches to controlling and abating unwanted sound.

Structural Acoustics Committee

Objectives and Focus of the Committee
The objectives of the Structural Acoustics Technical Committee are to provide a special forum for a free exchange of stimulating ideas and to disseminate the state-of-the-art technology of structural acoustics and related topics. The focus of this committee is on development and studies of new methodologies on both transient and steady-state acoustic radiation from vibrating structures, acoustic scattering, wave propagation, sound transmission, attenuation, and absorption, the effects of fluid-loading, mean flow, turbulence, etc., on dynamic and acoustic responses of elastic structures, as well as the applications of computer software to solve a variety of engineering noise control and reduction problems.

Aero/Hydro Acoustics Committee

Objectives and Focus of the Committee
The goal of the Aero/Hydro Acoustics Committee is to increase the understanding of mechanisms related to both sound and vibrations that are produced, and propagated, in air, water, or both (e.g. multi-phase flows).  This covers a wide range of sources and applications that are of interest to the academic community as well as industry.  Specific interests include source mechanisms, flow over internal and external features, turbomachinery noise, flow tones and fluid instabilities, measurement and analysis techniques, fluid-structure interaction, and mitigation methods.  Computational, analytical, and experimental methods are all welcome.
