ABSTRACT:
An apparatus for noise cancellation of ambient noise impinging upon the front surface of a pressure differential microphone on the end of a boom. The apparatus utilizes curved reflectors to cause ambient noise which impinges on the front surface of the microphone to also impinge on the back surface of the microphone. In addition, the curved reflectors cause a talker's voice which is directed toward the front surface of the microphone to be deflected away from the back surface of the microphone.
