Hangzhou Crysound Electronics Co., Ltd. Ear simulator/coupler CRY319

Description
2 cc coupled cavity, resonant frequency = 22.4 kHz CRY319 is a kind of coupled cavity with the volume of 2 cc in accordance with IEC 60318-5. It can be adapted to 1/2'' pressure-field measurement microphones according to IEC 61094-4 (WS2P), such as CRY372, CRY332, CRY334 and other measurement microphones. Hearing aids and headphones for air conduction are connected to the coupled cavity by ear inserts (e.g. ear molds or similar devices). The coupler has a resonant frequency of 22.4 kHz to avoid interference with measurements within the audible frequency range. This coupled cavity kit has a built-in CRY372 measurement microphone with the sensitivity of 12.5 mV/Pa and the noise floor of 20 dB(A).
