DESCRIPTION
This standard BS EN IEC 60645-3:2020 Electroacoustics. Audiometric equipment is classified in these ICS categories:
  • 13.140 Noise with respect to human beings
  • 17.140.50 Electroacoustics
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.
