标准摘要
[中文适用范围]： IEC 60645 的这一部分规定了描述短持续时间听力测试参考和测试信号的物理特性的方法及其测量方法。该标准的目的是确保以相同的方式指定和测量短持续时间的听力刺激，并使用规定的方法对使用此类信号的设备进行校准。本标准没有描述短持续时间测试信号的使用方法。 [外文原描述]： This part of IEC 60645 specifies a means of describing the physical characteristics of audiometric reference and test signals of short duration and methods for their measurement. The object of this standard is to ensure that audiometric stimuli of short duration are specified and measured in the same way and that the calibration of equipment using such signals is carried out using defined methods. This standard does not describe the method of use of short duration test signals. This second edition cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. Specific changes in this edition concern new figures of reference signals and changes in definitions.
