ICS Code (Electroacoustics): | 17.140.50 |
scope:
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.
