CRY318 Ear simulator/coupler
Compliant with IEC 60318-1, similar to the acoustic impedance of human ears
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 Ear Simulator is connected to CRY series testers and mainly used to test telephone receivers, headsets, and plug-in headphones, etc.
