Abstract This Stan
2、dard 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 S . - 1994 American National Standard Acoustical Termindogy in which more-generaliy-used terms in acoustics are
3、 defined, including a number of terms from physiological and psychological acoustics and music. Those terms from ANSI S1.1-1994 that are related to bioacoustics are included in this Standard as annexes.

Thes
5、e committees have wide representation from the technical community (manufacturers, consumers, and general-interest representatives). The Standards are published by the Acoustical Society of America through the American Institute of Physics as American National Stan- dards after approval by their res
6、pective standards committees and the American National Standards Institute. These standards are developed and published as a public service to provide standards useful to the public, industry, and consumers, and to Federal, State, and local governments. Each of the Accredited Standards Committees (o
7、perating in accordance with pro- cedures approved by ANSI) is responsible for developing, voting upon, and main- taining or revising its own Standards. The ASA Standards Secretariat administers committee organization and activity, and provides liaison between the Accredited Standards Committees and
8、ANSI. After the Standards have been produced and adopted by the Accredited Standards Committees, and approved as American National Standards by ANSI, an ASA Standards Secretariat arranges for their publication and distribution. An American National Standard implies a consensus of those substantially
9、 con- cerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necesarily una
10、nimity. Consen- sus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary: their existence does not in any respect preclude anyone, whether he or she has approved the Standard
11、or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standards. CAUTION NOTICE: An American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be ta
12、ken periodically to reaffirm, revise, or withdraw this Standard.

21、for information only and is not an integral part of American National Standard ANSI S3.20-1995 (ASA Catalog No. 114-19951.1 This Standard is a revision of, and supersedes, ANSI S3.20-1973 (RI9861 American National Standard Psychoacoustical Terminology, which was developed to provide a unified compil
22、ation of terms and definitions used in the area of human psychoacoustics. Since the original preparation of ANSI S3.20- 1973, Accredited Standards Committee S3, Bioacoustics, has developed several Standards incorporating new terminology. Further, some confusion has developed concerning the definitio
23、n of several terms incorporated in some American National Standards, for the most part because slightlv different definitions have been used in different standards. This revision of ANSI 53.20-1 973 (R1986) has been developed taking into account both older and newer terminology and has been retitled
24、 Bioacoustical Terminology. Overall, this revision provides a unified compilation of terms and definitions commonly used in human bioacoustics including hearing, psycho- acoustics, speech, and physiological acoustics. It is intended to be a counterpart and supplement to ANSI S1.l-1994 American Natio
25、nal Standard Acoustical Terminology which provides terms and definitions basic to general acoustics, but also includes some terms related to human bioacoustics. Those terms from ANSI SI, 1-1 994 that relate directly to human bioacoustics are included in this Standard as annexes, along with certain o
26、ther terms of general use in human bioacoustics. This Standard was developed under the jurisdiction of Accredited Standards Committee S3, Bioacoustics, which has the following scope: Standards, specifications, methods of measurement and test, and terminolog y, in the fields o fps ychoiogical and phy
27、siological acoustics, including aspects of general acoustics, shock and vibration which pertain to biological safety, tolerance, and comfort.

Some additional general terms for measurement and instruments related to applications in psy- choacoustics are also provided
31、. 1.2 Purpose The purpose of this Standard is to provide a unified compilation of common terminology for use in the discipline of human bioacoustics including hearing, speech, psychoacoustics, and physiological acoustics. This Standard is intend- ed to be a counterpart and supplement to ANSI S 1 -1
32、-1 994 American National Standard Acousti- cal Terminology which provides terms and definitions used in general acoustics. 1.3 Application The terms and definitions provided in this Stan- dard may be used in any publication concerned with human bioacoustics including scientific articles and, particu
33、larly, American National Standards. The terms take into consideration not only past usage but best current practice. Use of these definitions in future documents is strongly encouraged. Acoustical terms of more general use in the performance of acoustical measurements, the properties of electroacous
34、tic transducers, and applications in the fields of architectural acou- stics, environmental acoustics, underwater sound, and music are provided in ANSI SI. 1- 1 994 American National Standard Acoustical Terminology. A selected set of terms from clause 4 of ANSI S1 .I -1 994 involving acoustical leve
35、ls is listed here in annex A, and terms from clause 7 on transducer and linear system proper- ties are included here as annex B. The entire clause 12 of ANSI SI. 1-1 994 containing psycho- acoustics and physiological acoustical terminol- ogy is included here in annex C, and the entire clause 13 on m
36、usical acoustics is included here in annex D. All terms defined in the body of the text and in the annexes are listed in an aiphabeti- cal index. Terms of special use in the field of human expo- sure to mechanical vibration and shock are contained in ANSI S3.32-1982 (R1990) Ameri- can National Stand
