Acoustics - Reference zero for the calibration of audiometric equipment - Part 3: Reference equivalent threshold force levels for pure tones and bone vibrators (ISO 389-3:1994, including Technical Corrigendum 1:1995); German version EN ISO 389-3:1998.
Most recent standard

Summary

The document specifies the following data applicable to the calibration of bone vibrators for pure-tone bone conduction audiometry: a) Reference equivalent threshold force levels, corresponding to the threshold of hearing of young otologically normal persons by borne-conduction audiometry. b) Essential characteristics of the bone vibrator and of its method of coupling to a person under test and to the mechanical coupler. c) Essential characteristics and datum level of the masking noise applied to the ear not under test.

Notes

A transition period, as set out in DIN EN ISO 389-3 (2016-06), exists until 2016-08-31.
