GRAS RA0039 Ear Simulator according to IEC 60318-1
Volume: Complex
ANSI: S3.7
IEC: 60318-1
The GRAS 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".
Technology
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”.
The RA0039 is also part of the GRAS 43AA Artificial Ear and GRAS 43AD Artificial Ear.
