Reference sound source JS1001 series

The mouth simulators of JS1001 series are used to simulate the sound source of the sound field near the mouth of a person, which is suitable for the acoustic parameters testing of telephone transmitters and microphones. Its frequency response curve and other properties comply with the international requirements of IEEE 269, 661 as well as the requirement for "mouth reference point" for transmitting acoustic signals in ITU-T P51. JOJO-JS1001 artificial mouth is a standard sound source for acoustic measurement.
