Listen supplies artificial mouths, ears and ear couplers from Brüel and Kjær, GRAS and more.
Mouth Simulators such as the B&K Type 4227 or the GRAS 44AA/44AB are designed to test telephone transmitters and other microphones where a sound field similar to the human voice field is required. They can also be used as an accurate reference source for near field testing of handsets and microphones. They are commonly used for testing to the IEEE 269, 661 and ITU-T Rec. P.51 standards.
