《GB/T 7341.4-1998听力计 第4部分 延伸高频测听的设备》由TC23（全国电声学标准化技术委员会）归口，主管部门为工业和信息化部（电子）。
本标准除了那些能适用的并已在GB/T 7341.1中作出规定的要求之外，对在频率范围从8000Hz～16000Hz作纯音测听使用而设计的测听设备的要求予以规定。本标准的目的是为了保证使用符合本标准的不同类型的设备，在一给定人耳上进行延伸高频测听时，应给出基本相同的结果。
Scope
In addition to the applicable requirements specified in GB/T 7341.1, this standard specifies the requirements for audiometry equipment designed for pure tone audiometry in the frequency range from 8000Hz to 16000Hz. The purpose of this standard is to ensure that the use of different types of equipment conforming to this standard, when performed on a given human ear for extended high-frequency audiometry, should give substantially the same results.
