电声学 助听器的真耳声学特性的测量设备

[中文适用范围]： 本国际标准规定了设计用于测量助听器真耳声学特性的测试设备的一般要求，并描述了所使用的术语。本国际标准的目的是确保使用符合本国际标准的不同测试设备，使用 ISO 12124 中描述的方法对助听器在给定人耳上的真耳声学特性进行测量，应给出基本相同的结果。结果。 [外文原描述]： Specifies the general requirements for test equipment designed for use in measuring the real-ear acoustical characteristics of hearing aids and describes the terminology used. The purpose of this International Standard is to ensure that measurements of real-ear acoustical characteristics of a hearing aid on a given human ear, performed with different test equipment which comply with this International Standard using methods described in ISO 12124, shall give substantially the same results.
