Electroacoustics - Simulators of human head and ear - Part 3: Acoustic coupler for the calibration of supra-aural earphones used in audiometry (IEC 60318-3:1998); German version EN 60318-3:1998.
Preview
Summary
The document describes an acoustic coupler for loading supra-aural audiometric earphones as specified in ISO 389-1 with a specified acoustic impedance, when calibrating audiometers, in the frequency range of 125 Hz to 8.000 Hz. The sound pressure developed by an earphone is not, in general, the same in the coupler as in person's ear. However, the IEC recommends its use as a simple and ready means for the exchange of specifications on audiometers and for the calibration of specified earphones used in audiometry.
Notes
A transition period, as set out in DIN EN 60318-3 (2015-09), exists until 2018-01-15.
