ASA S3.13-1987 (R2020)
American National Standard for Mechanical Coupler for Measurement of Bone Vibrators
standard by American National Standards of the Acoustical Society of America, 11/16/1987
Full Description
This standard specifies requirements for mechanical couplers used for calibrating bone-conduction audiometers and making measurements on bone vibrators and bone-conduction hearing aids. Specific design features are given for the mechanical coupler when driven by a vibrator with a prescribed plane circular tip area and applied with a specific static force. An appendix provides an example of a specific construction of a mechanical coupler.
