Electroacoustics - Audiometric equipment - Part 3: Test signals of short duration
IEC 60645-3:2020 specifies a means of describing the physical characteristics, in terms of electrical waveforms, of audiometric reference and test signals of short duration and methods for their measurement.The object of this document 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 document does not describe the method of use of short-duration test signals.IEC 60645-3:2020 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) new figures of reference signals;b) changes in definitions.

Electroacoustics - Audiometric equipment - Part 3: Test signals of short duration
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.
