CRY3605 mouth simulator is a sound source which simulates the sound field around the human mouth at close quarters. Extremely low distortion, with distortion levels reaching international leading standards from 200Hz to 10kHz. 

Suitable for conducting acoustic characteristic tests of household and similar appliances, information technology devices, audio, video, and similar electronic equipment under real working conditions.

CRY3602 mouth simulator is a sound source used to simulate the sound field near the human mouth. Widely used for testing acoustic parameters such as frequency response and distortion in telephony transmitters and microphones. 

It has a built-in power amplifier with the gain of 20dB. It can connect with sound card or signal generator directly without buying additional power amplifier, that simplifies the connection of test system.

CRY3603 high frequency mouth simulator is used to simulate high frequency sound sources in the sound field near the human mouth.Frequency response up to 40kHz.

Mainly used in high-frequency microphone frequency response , distortion and other acoustic parameter index test. Meet the demand of high frequency acquisition test.
