IEC 61669:2015给出了测量和估计空气传导助听器的实际耳声性能特征，以及测量与助听器应用相关的耳的某些声学特性的建议和要求。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适用于所使用的测试信号和所采用的条件。本标准的目的是确保- 给定助听器在给定人耳上的耳声性能特征可以通过其他测试设备在其他位置复制。第二版取消并取代了IEC 61669:2001第一版和ISO 12124:2001第一版。本版为技术修订版。

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.
