This part of ISO389 specifies the following data applicable to the calibration of bone vibrators for pure-tone bone-conduction audiometry: reference equivalent threshold vibratory force levels (RETVFL), corresponding to the threshold of hearing of young otologically normal persons by bone-conduction audiometry; essential characteristics of the bone vibrator and the method of coupling to the test subject, and to the mechanical coupler; essential characteristics of the masking noise and the baseline masking noise level applied to the ear not under test. Guidance on the practical application of this part of ISO389 in the calibration of audiometers is given in AnnexB. RETVFL is the vibratory force level transmitted to a mechanical coupler of specified characteristics by a vibrator when applied to the mechanical coupler under stated conditions of test and when energized at the voltage level corresponding to the normal threshold of hearing for location on the mastoid prominence. NOTE 1 Values for the differences in reference equivalent threshold vibratory force levels between location on the forehead and mastoid are included for information in AnnexC. NOTE 2 Recommended procedures for carrying out bone-conduction audiometry are specified in ISO8253-1.
