Scope

This International Standard 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 a 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. note:1) To be published.
