Ear simulator CRY3711

precision

Key Specifications Dynamic Range: 23 dBA to 160 dB Frequency Range: 100 Hz to 10 kHz ±1 dB Applications Hearing aids measurements Insert earphone measurements Standards IEC 60318-4 Electroacoustics - Simulators of human head and ear - Part 4 ITU-T P.57 Type 2 The CRY3711 ear simulator simulates the way an earplug conduit is inserted into the ear canal or auricle to measure headphone performance. It has a 1/2 inch prepolarized pressure field measurement microphone inside and can be used for acoustic testing of high-quality in-ear headphones. The input impedance of CRY3711 is very close to the input impedance of an ordinary human ear, enabling effective measurement up to 10 kHz.
