IEC EN 60645-3 Electroacoustics - Audiometric Equipment - Short Term Test Signals

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60645-3 testing. IEC EN 60645-3 specifies measurement methods and a way to describe the physical properties of short-term audiometric reference and test signals in terms of electrical waveforms.

The purpose of this standard is to ensure that short-duration audiometric stimuli are identified and measured in the same way and that equipment calibration using such signals is carried out using defined methods. This standard does not describe the method of using short-term test signals.

Advances in the field of hearing measurements for diagnosis, hearing protection and rehabilitation have resulted in the availability of a wide variety of audiometers. In addition, it is possible to think of the audiometer as a set of independently definable functional units. By identifying these functional units, it is possible to determine the performance of other audiometric equipment using these units.

Examples of test methods in which such signals are commonly used are the recording of brainstem evoked potentials and evoked otoacoustic emissions. Reference signals are explained to provide a basis for calibration and as a recommendation for use when there is no particular reason to have an alternative signal. The method for measuring acoustic and vibrating signals is described.
