IEC 60118-0:20 22给出了使用声学耦合器或闭塞耳模拟器测量空气传导助听器性能特征的测量建议。本文件适用于助听器电声特性的测量和评估，例如用于型式试验和制造商数据表。本文件也适用于出于生产、供应和交付质量保证目的的助听器性能特征的测量。通过本文件中规定的方法获得的测量结果将表示测量条件下的性能，并且可能与助听器在实际使用条件下的性能有很大偏差。本文档主要使用符合IEC 60318-图5仅用于装载具有指定声阻抗的助听器，而不用于再现人耳中的声压。对于反映正常人耳中的输出水平的测量，可以使用根据IEC 60318-4的闭塞耳模拟器。对于扩展的高频测量和深度插入助听器，可以使用符合IEC 60318-8的声学耦合器。本文件还涵盖了具有非声学输入（如无线、感应或电输入）的助听器的测量。本文件不涵盖助听器在模拟现场工作条件下的测量，IEC 60118-8可适用于此。本文档不涵盖助听器在典型用户设置下的测量以及使用语音-类似的信号，可以应用IEC 60118-15。IEC 60118-0:20 22合并并更新了IEC 60118-0:20 15和IEC 60118-7:20 05中先前描述的方法。它取消并取代了2015年发布的IEC 60118-0第三版。本版构成技术修订版。IEC 60118-7:20 05中描述的质量控制测量可参见本文件第10条。与之前的版本相比，此版本包括以下重大技术变更:a)根据IEC 60318-5的声学耦合器的默认使用，b)添加根据IEC 60318-4的闭塞耳模拟器的可选使用，c)当需要关于高于8kHz的响应的信息时，增加根据IEC 60318-8(基于IEC TS 62886的新标准)的声学耦合器的可选使用，或者根据IEC 60318-8的声学耦合器的可选使用。8用于深插入式助听器，d)为生产、供应和交付质量保证目的增加助听器性能的测量，e)校正和更新测量配置和方法，增加使用顺序测量作为优选配置，f)更新和扩展了助听器的非声学输入的测量程序。

IEC 60118-0:2022 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.
IEC 60118-0:2022 merges and updates the methods previously described in IEC 60118-0:2015 and IEC 60118-7:2005. It cancels and replaces the third edition of IEC 60118-0 published in 2015. This edition constitutes a technical revision.
Measurements for quality control as described in IEC 60118-7:2005 can be found in Clause 10 of this document.
This edition includes the following significant technical changes with respect to previous editions:
a) the default use of an acoustic coupler according to IEC 60318-5,
b) addition of the optional use of an occluded ear simulator according to IEC 60318-4,
c) addition of the optional use of an acoustic coupler according to IEC 60318-8 (new standard based on IEC TS 62886) when information about the response above 8 kHz is needed, or the optional use of the acoustic coupler according to IEC 60318-8 for deep insert hearing aids,
d) the addition of measurements of the performance of hearing aids for production, supply and delivery quality assurance purposes,
e) corrected and updated measurement configuration and methods, adding the use of a sequential measurement as preferred configuration,
f) updated and expanded measurement procedures for the non-acoustic inputs of the hearing aid.
