专家解读视频
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 IEC 60373. 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 chosen are practical and reproducible and are based on selected fixed parameters.
