scope:

This American National Standard provides definitions for terms used in human bioacoustics. Some additional general terms for measurement and instruments related to applications in psychoacoustics are also provided.

Acoustical terms of more general use in the performance of acoustical measurements, the properties of electroacoustic transducers, and applications in the fields of architectural acoustics, environmental acoustics, underwater sound, and music are provided in ANSI/ASA S1.1-2013 American National Standard Acoustical Terminology. A selected set of terms from clause 3 of ANSI/ASA S1.1-2013 involving acoustical levels is listed here in Annex A, and terms from clause 6 on transducer and linear system properties are included here as Annex B. The entire clause 11 of ANSI/ASA S1.1-2013 containing psychoacoustics and physiological acoustical terminology is included here in Annex C, and the entire clause 12 on musical acoustics is included here in Annex D. All terms defined in the body of the text and in the annexes are listed in an alphabetical index.
