Directional microphones are used in PC voice and telephony applications to reduce the pickup of noise and reverberation, as well as reduce loudspeaker-to-microphone acoustic coupling. Differential-type directional microphones are popular because of their small size and relatively low cost. This talk focuses on how differential microphone technology has been used in new products and solutions developed by AT&T intelligent acoustic systems for the PC multimedia industry.
