Electroacoustics. Hearing aids. Part 0: Measurement of the performance characteristics of hearing aids (IEC 60118-0:2022)

Alkalmazási terület

This part of IEC 60118 gives recommendations for the measurement of the performance characteristics of air conduction hearing aids measured with an acoustic coupler or occluded ear simulator. This document is applicable to the measurement and evaluation of the electroacoustical characteristics of hearing aids, for example for type testing and manufacturer data sheets. This document is also applicable for the measurement of the performance characteristics of hearing aids for production, supply and delivery quality-assurance purposes. The measurement results obtained by the methods specified in this document will express the performance under conditions of the measurement and can deviate substantially from the performance of the hearing aid under actual conditions of use. This document primarily uses an acoustic coupler according to IEC 60318-5 which is only intended for loading a hearing aid with specified acoustic impedance and is not intended to reproduce the sound pressure in a person's ear. For measurements reflecting the output level in the normal human ear the occluded ear simulator according to IEC 60318-4 can be used. For extended high-frequency measurements and for deep insert hearing aids, the acoustic coupler according to IEC 60318-8 can be used. This document also covers measurement of hearing aids with non-acoustic inputs, such as wireless, inductive or electrical input. This document does not cover the measurement of hearing aids for simulated in situ working conditions, for which IEC 60118-8 can be applied. This document does not cover the measurement of hearing aids under typical user settings and using a speech-like signal, for which IEC 60118-15 can be applied.
