IEC EN 60645-2 Audiometers - Test for Speech Audiometry

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60645-2 testing. This standard specifies requirements for audiometers or parts thereof designed to provide a means of presenting speech sounds to a subject in a standardized manner, for example for measuring speech recognition.

Audiometers are classified into four types: Type A devices provide a wide range of conveniences, while type B provides only basic facilities. For both types, the audiometer can be calibrated for the headphones' free field equivalent output level and then designated as either AE or BE type.

This standard excludes requirements for speech audiometers provided with frequency response adjustments aimed at determining the optimal intelligibility frequency response curve for each subject.

The purpose of this standard is to ensure that hearing tests using speech as the test stimulus, performed on a given human ear with different audiometers conforming to this standard, will yield substantially the same results for a given calibration method.

If the audiometer has as an integral part means to replay recorded speech material, the fit tests should be performed using the recording of the required test signals. If the playback device is not an integral part of the audiometer, test signals should be applied to the audiometer's electrical input.
