电声学. 助听器真耳声学性能特征的测量

[中文适用范围]： 本国际标准对气导助听器真耳声学性能特性的测量和估计以及与助听器应用相关的某些耳朵声学特性的测量提出了建议和要求。采用非线性或分析处理技术的助听器的真耳声学特性测量仅对所使用的测试信号和所采用的条件有效。该标准的目的是确保可以使用其他测试设备在其他位置复制给定助听器在给定人耳上的真耳声学性能特征的测量结果。 [外文原描述]： IEC 61669:2015 gives recommendations and requirements for the measurement and estimation of the real-ear acoustical performance characteristics of air-conduction hearing aids and for the measurement of certain acoustic properties of the ear related to the application of hearing aids. Measurements of real-ear acoustical characteristics of hearing aids which apply non-linear or analytical processing techniques are valid only for the test signals used and conditions employed. The purpose of this standard is to ensure that measurements of real-ear acoustical performance characteristics of a given hearing aid on a given human ear can be replicated in other locations with other test equipment. This second edition cancels and replaces the first edition of IEC 61669:2001 and the first edition of ISO 12124:2001. This edition constitutes a technical revision.
