Electroacoustics. Simulators of human head and ear - Ear simulator for the measurement of supra-aural and circumaural earphones Ingestion-build-228203 be used as a guide1 Scope This part of IEC 60318 specifies an ear simulator for the measurement of supra aural and circumaural earphones (used for example in audiometry and telephonometry) applied to the ear without acoustical leakage, in the frequency range from 20 Hz to 10 kHz. The same device can be used as an acoustic coupler at additional frequencies up to 16 kHz. NOTE 1 This device has alternative configurations for supra aural earphones and different types of
