The Acoustical Society of America (ASA) is an international scientific society dedicated to increasing and diffusing the knowledge of acoustics and its practical applications. The ASA was instigated by Wallace Waterfall, Floyd Watson, and Vern Oliver Knudsen. On December 27, 1928, approximately 40 scientists and engineers interested in acoustics met at the Bell Telephone Laboratories in New York, NY, to consider the formation of a scientific society for acoustics. Just a few months later, the Acoustical Society of America held its first meeting on May 10-11, 1929, with approximately 450 charter members. In 1931 the Acoustical Society joined with three other scientific societies to form the American Institute of Physics. The Society has 13 technical committees that represent specialized interests in the field of acoustics. The committees organize technical sessions at conferences and are responsible for the representation of their sub-field in ASA publications.
