Abstract
An apparatus for noise cancellation of ambient noise impinging upon the front surface of a pressure differential microphone. 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 deflect a speaker's voice which is directed toward the front surface of the microphone to be deflected away from the back surface of the microphone.
