Electroacoustics - Simulators of Human Head and Ear - Part 3: Acoustic Coupler for the Calibration of Supra-aural Earphones Used in Audiometry (a nationally adopted international standard)
This standard specifies an acoustic coupler for objective and reproducible measurements of supraaural audiometric earphones in the frequency range from 125 Hz to 8000 Hz. The results of these measurements can be used for specifying reference equivalent threshold sound pressure levels (RETSPL) for the calibration of audiometers.
