Description

The Bruel & Kjaer Type 4227 Mouth Simulator is a stable, low distortion sound source used for the testing of acoustic transducers. When testing telephone transmitters and close talking microphones it is required that the sound field closely replicates the sound field generated by the human mouth. Type 4227 consists of a high quality loudspeaker mounted in a specially shaped housing. A lip ring is mounted on the upper surface of the unit, providing a convenient reference plane for measurements.


Product Family: Type 4227
