CRY318 Ear Simulator Set
The CRY318 ear simulator is a type of human ear simulator that simulates the average human ear impedance.
When coupled to a sound source, an acoustic impedance load similar to human ears can be loaded onto the sound source. With IEC 60318-1 compliant standard design, 1/2″ pressure field measurement microphone (CRY372) and preamplifier (CRY508), CRY318 is connected to CRY series testers and mainly used to test telephone receivers, headsets and plug in headphones and more.
