The ASA S1.1-2013 (R2020) Acoustical Terminology Standard strives to offer precise and consistent definitions for words used in the acoustics and electroacoustics fields. Architectural acoustics, engineering acoustics, physical acoustics, physiological and psychological acoustics, sonics and ultrasonics, underwater sound, and music are only a few of the many subfields it covers within the field of acoustics.

The standard also recognises that distinct standards included in the document address specialised concepts pertaining to vibration and shock, psychoacoustics, and bioacoustics. The definitions offered in this standard are in line with their equivalents in those international standards to ensure compatibility with them.

It should be noted that this version of the standard omits definitions for words used in sound recording and reproduction. Such phrases are acknowledged as better suited for inclusion in other specific standards.
