Electroacoustics - Simulators of Human Head and Ear - Part 1: Ear Simulator for the Calibration of Supra-Aural Earphones
|Publication Date:||1 July 1998|
|ICS Code (Electroacoustics):||17.140.50|
This International Standard relates to the specification of an ear simulator which covers the frequency band 20 Hz to 10 000 Hz and is intended for calibrating supra-aural earphones used in audiometry and telephonometry applied to the ear without acoustical leakage.
NOTE - This device is not intended for the calibration of circumaural earphones. However, IEC 60318-2 specifies an adaptor for use with this ear simulator to provide an interim acoustic coupler for the calibration of a circumaural audiometric earphone.
