standards: from the society's inception, its members have been involved in the development of acoustical standards concerned with terminology, measurement procedures, and criteria for determining the effects of noise and vibration. In 1932, the american national standards institute (ansi), then called the american standards association, appointed the acoustical society as sponsor of a committee, designated as z-24, to standardize acoustical terminology and measurements. The work of this committee expanded to such an extent that it was replaced in 1957 by three committees, s1 on acoustics, s2 on mechanical shock and vibration, s3 on bioacoustics, s12 on noise, added in 1981 and a fifth, s3, sc1 animal bioacoustics added in 2007. These committees are each responsible for developing a consensus for, and adopting standards in accordance with procedures approved by ansi. Although these committees are independent of the acoustical society, the society provides the financial support and an administrative secretariat to facilitate their work. More than 100 acoustical standards have been published in this way. The society also provides administrative support for several international standards committees and acts as the administrative secretariat (on behalf of ansi) for the international technical committee on vibration and shock (tc-108). Scope of asc s1: standards, specifications, methods of measurement and test, and terminology in the field of physical acoustics including architectural acoustics, electroacoustics, sonics and ultrasonics, and underwater sound, but excluding those aspects which pertain to biological safety, tolerances and comfort. Scope of asc s2: standards, specification, methods of measurement and test, and terminology in the field of mechanical vibration and shock, and condition monitoring and diagnostics of machines, including the effects of exposure to mechanical vibration and shock on humans, including those aspects which pertain to biological safety, tolerance and comfort. Scope of asc s3: standards, specifications, methods of measurement and test, and terminology in the fields of psychological and physiological acoustics, including aspects of general acoustics, which pertain to biological safety, tolerance and comfort. Scope of asc s3/sc 1: standards, specifications, methods of measurement and test, instrumentation and terminology in the field of psychological and physiological acoustics, including aspects of general acoustics, which pertain to biological safety, tolerance and comfort of non-human animals, including both risk to individual animals and to the long-term viability of populations. Animals to be covered may potentially include commercially-grown food animals; animals harvested for food in the wild; pets; laboratory animals; exotic species in zoos, oceanaria or aquariums; or free-ranging wild animals. Scope of asc s12: standards, specifications, and terminology in the field of acoustical noise pertaining to methods of measurement, evaluation, and control; including biological safety, tolerance and comfort, and physical acoustics as related to environmental and occupational noise.

meetings: the asa holds 2 meetings each year typically attracting about 1000 attendees each. Meetings provide the venue for the exchange of scientific information among scientists worldwide. Meetings include technical sessions with 800 to 1300 individual presentations, technical committee meetings, standards committee meetings, and events for social networking.
