ACOUSTICS - REFERENCE ZERO FOR THE CALIBRATION OF AUDIOMETRIC EQUIPMENT - PART 3: REFERENCE EQUIVALENT THRESHOLD VIBRATORY FORCE LEVELS FOR PURE TONES AND BONE VIBRATORS
12-01-2013
Provides 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.
