Abstract
A microphone for use in a harsh environment of intense vibration and sound pressure. A microphone transducer and an acceleration transducer are located adjacent each other inside of a housing. The microphone transducer substantially blocks much of the acoustic signal from reaching the acceleration transducer. Accordingly, the acceleration transducer provides a signal substantially related only to the movement of the microphone, while the microphone transducer provides a signal related to both the movement of the microphone and the acoustic signal applied to it. The acceleration signal may then be removed from the microphone signal, providing a electrical signal substantially representative only of the acoustic signal.
