ANSI/ASA S3.13-1987 (R2012)

Vendor Note: This standard specifies requirements for mechanical couplers used for calibrating bone- conduction audiometers and makingmeasurements on bone vibrators and bone- conduction hearing aids. Specific design features are given for the mechanicalcoupler when driven by a vibrator with a prescribed plane circular tip area and applied with a specific static force. An appendixprovides an example of a specific construction of a mechanical coupler.
