Load simulator CRY318

precisionear

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. Robust stainless steel design Leading technology Compliance with international standards 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 Elaborate design, sophisticated materials and precision manufacturing ensure excellent product consistency. Equipped with CRY372 pressure-field pre-polarization measurement microphone, it can give its performance into full play.
