IEC 711 ear simulator RA0045
|
The IEC 711 Ear Simulator Type RA0045 is an ear simulator with an input impedance closely resembling that of an average human ear. The RA0045 includes a Type 40AG pressure microphone and each RA0045 is individually calibrated with this specific microphone. The RA0045 meets the requirements of IEC 60711:1981 Occluded-ear simulator for the measurement of earphones coupled to the ear by ear inserts. The RA0045 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 RA0045 is also part of the G.R.A.S. Artificial Ear Type 43AC. It can also be used with either of the Pinna Simulators RA0056 or RA0057 to simulate a complete ear for testing telephones and loudspeakers. | Related_Products: Adobe Acrobat reader is required for viewing data sheets.
