The RA0056 Low-leak pinna simulator is used for tests which simulate a telephone or handset held comfortably against the listeners ear.
The RA0056 meets the specifications in the ITU-T Recommendation P.57 (08/96) "Series P: Telephone transmission quality, Objective measuring apparatus: Artificial ears".
To simulate a telephone or handset held slightly away from the listeners ear use the RA0057 High-leak pinna simulator.
