标准简介
Defines a method of expressing the input output ratio as an acousto mechanical sensitivity level measured on a mechanical coupler according to the second edition of publication 373. (in preparation). Provides a suitable basis for the exchange of information or for direct comparison of the electroacoustic characteristics of hearing aids using bone vibrator outputs. The methods are chosen to be practical and reproducible and are based on selected fixed parameters.
