适用范围

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.#,,#
