Measurement Transducers for Audio Measurement
For accurate testing of headphones, microphones telephones and loudspeakers
SoundCheck is compatible with any brand of artificial mouth, ear coupler, head and torso simulator and more, for example, those from Brüel and Kjær, GRAS and others.
Ear Couplers
Our own low-cost 0.4cc ear coupler, or third party products such as the B&K Type 4946 or the GRAS RA0038 offer repeatable results for production line testing of hearing aids and headphones.
Artificial Ears
Artificial Ears such as the B&K Type 4153 or the GRAS 43AA are designed for carrying out electroacoustical measurements on earphones and headphones under well defined acoustical conditions. They have an acoustical impedance similar to that of the human ear and fulfil the requirements of IEC 60318-1.
Mouth Simulators
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.
Head and Torso Simulators (HATS)
Head and Torse simulators are valuable for obtaining realistic in-situ measurements of headphones, telephones or hearing aids. Head and Torse simulators include the Bruel and Kjaer type 5128-C high frequency HATS or the older Type 4128D, or GRAS Kemar. These have built-in ear and mouth simulators that provide a realistic reproduction of the acoustic properties of an average adult human head and torso. They are commonly used for tests on telephone handsets, headsets, audio conference devices, microphones, headphones, hearing aids and hearing protectors.
Headphone Test Fixtures
Headphone Test Fixtures offers reproducible positioning of the DUT for accurate production line headphone and headset measurements.
