Simulator
100 - 4 000 Hz | RA0039 G.R.A.S. Sound & Vibration

Description

The G.R.A.S. IEC 318 RA0039 Ear Simulator is an ear simulator with an input impedance closely resembling that of an average human ear. When the RA0039 is coupled to a sound source, the impedance will load the sound source similar to the loading caused by the human ear.

The RA0039 meets the requirements of IEC 60318-1:1998 Electroacoustics - "Simulators of human head and ear - Part 1: Ear simulator for the calibration of supra-aural earphones".

The RA0039 is measured and calibrated according to the ITU-T Recommendation P.57 (08/96) ”Series P: Telephone transmission quality, Objective measuring apparatus: Artificial ears
