CRY712 High-leak pinna for ear simulator
Compliance with ITU-T Rec. P.57 (2011) Type 3.2 specification
CRY712 High-Leak Pinna for Ear Simulator is a wide-band ear simulator for testing calls. It is designed to measure the actual response of a telephone call. CRY712 High-Leak Pinna for Ear Simulator can simulate the average human ear loss of the telephone handset far away from the human ear (high leakage). It should be used with the ear simulator (CRY711) and preamplifier in accordance with IEC 60318-4. Such High-Leak Pinna for Ear Simulator is equipped with a soft sealing ring, which ensures a good seal between the ear simulator and the surface of the product under test, and prevents the product under test from being scratched.
