ANSI/ASA S3.20-2015 (Revision of ANSI S3.20-1995) AMERICAN NATIONAL STANDARD Bioacoustical Terminology Secretariat: Acoustical Society of America Approved on October 22, 2015 by: American National Standards Institute, Inc. Abstract This standard pr

    4、ovides definitions for a wide variety of terms used in human bioacoustics, including hearing, speech, psychoacoustics, and physiological acoustics. It is intended to supplement ANSI/ASA S1.1-2013 American National Standard Acoustical Terminology in which more generally used terms in acoustics are de

    5、fined, including a number of terms from physiological and psychological acoustics and music. Those terms from ANSI/ASA S1.1-2013 that are related to bioacoustics are included in this Standard as annexes. 2015 Acoustical Society of America All rights reserved ii Foreword This Foreword is for informat

    6、ion only, and is not a part of the American National Standard ANSI/ASA S3.20-2015 American National Standard Bioacoustical Terminology. As such, this Foreword may contain material that has not been subjected to public review or a consensus process. In addition, it does not contain requirements neces

    7、sary for conformance to the standard. This standard comprises a part of a group of definitions, standards, and specifications for use in bioacoustics. It was developed and approved by Accredited Standards Committee S3 Bioacoustics, under its approved operating procedures. Those procedures have been

    8、accredited by the American National Standards Institute (ANSI). The Scope of Accredited Standards Committee S3 is as follows: Standards, specifications, methods of measurement and test, and terminology in the fields of psychological and physiological acoustics, including aspects of general acoustics

    9、 which pertain to biological safety, tolerance and comfort. This standard is a revision of ANSI S3.20-1995, which has been technically revised. New terms have been added, deprecated terms removed, and a number of terms have had their definitions updated. The normative references have been updated, a

    10、nd updated terms from ANSI/ASA S1.1-2013 appear in the annexes. Additional information has been added in blue font to some of the terms in the annexes for completeness, clarity, and consistency in bioacoustics. This standard is not comparable to any existing ISO Standard. At the time this Standard w

It and the boundary ridges contribute to sound source direction and location. It also aids fitting and retention of ear molds

    44、 in the meatus. NOTE Of the visible and identified anatomical features of the pinna, the concha and tragus together are acoustically its most important features because of their shape, dimensions and location relative to and surrounding the entrance to the ear canal. 3.18 contralateral reflex; cross

    45、ed reflex. Middle-ear muscle reflex that is elicited in the ear contralateral (opposite) to the stimulus ear. When the stimulus is acoustic, the resulting middle-ear muscle reflex is sometimes called contralateral acoustic reflex or crossed acoustic reflex. 3.19 cross hearing. Phenomenon in which so
