This Standard provides definitions for a wide variety of terms used in human bioacoustics, including hearing, speech, psychoacoustics, and physiological acoustics. It is intended to supplement ANSI S1.1-1994 American National Standard Acoustical Terminology in which more-generally-used terms in acoustics are defined, including a number of terms from physiological and psychological acoustics and music. Those terms from ANSI S1.1-1994 that are related to bio acoustics are included in this Standard as annexes.
