Summary
This part of ISO 389 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 bone-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
DIN EN ISO 389-3 (1999-07) remains valid alongside this standard until 2016-08-31.
