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.

Standard compliant:

IEC 60318-1:2009 Electroacoustics – Simulators of human head and ear – Part 1: Ear simulator for the measurement of supra-aural and circumaural earphones
GB/T 25498.1-2010 Electroacoustics – Simulators of human head and ear – Part 1: Ear simulator for the measurement of supra-aural and circumaural earphones
ITU-T Rec. P.57(2011) Type 1 artificial ear

We calibrate ear simulators.
