<p>An apparatus (20) for noise cancellation of ambient noise impinging upon the front surface of a pressure differential microphone (22) on the end of a boom (32). The apparatus utilizes curved reflectors (24 and 25) to cause ambient noise which impinges on the front surface of the microphone (22) to also impinge on the back surface of the microphone. In addition, the curved reflectors (24 and 25) cause a talker's voice which is directed toward the front surface of the microphone to be reflected away from the back surface of the microphone.</p> |
