CRY605 Mouth simulator

CRY605 Mouth Simulator is used to simulate the sound source of the sound field near the mouth of a person, and is suitable for the acoustic parameters testing of telephone transmitters and microphones, such as frequency response and distortion. It meets the requirements of the international standards IEEE 269 and IEEE 661 and the requirement for "mouth reference point" for transmitting acoustic signals in ITU-T P51.
