EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60645-1 testing. IEC EN 60645-1 specifies general requirements for audiometers and specific requirements for pure-tone audiometers designed for use in determining hearing threshold levels against standard reference threshold levels established through psychoacoustic testing methods.
The purpose of this standard is to provide:
This standard describes performance requirements for pure tone audiometry designed for measurement of hearing in the frequency range 125 Hz to 16 kHz, and for speech audiometry designed to perform live or recorded speech audiometry.
When speech signal facilities are provided by an audiometer, performance requirements are given for both live sound and recorded speech material. Although live sound speech audiometry may not meet the requirements of this standard, it is widely practiced especially in children and therefore a specification has been included to ensure as high a degree of reliability as possible. This standard does not specify the speech material used for testing purposes or the required acoustic properties of the test chamber.
Speech audiometers use headphones or speakers to present signals to the test subject. In this standard, characteristics of the performance characteristics of speech audiometers and the associated calibration and test methods are given according to both the free field equivalent output level method and the uncorrected ear simulator or acoustic coupler output level method.
