This part of IEC60318 specifies an acoustic coupler for the measurement of supra-aural audiometric earphones in the frequency range from 125Hz to 8000Hz. The sound pressure developed by an earphone is not, in general, the same in the coupler as in a person\'s ear. However, the acoustic coupler can be used as an objective and reproducible means of measuring the output of supra-aural earphones. It can be used for specifying reference equivalent threshold sound pressure levels (RETSPL) for the calibration of audiometers.
