  • Patent number: 6072880
    Abstract: A modular Active Noise Control exhaust silencing system is provided including a housing defining an acoustic enclosure having an acoustic outlet port. A speaker is disposed within the acoustic enclosure and an amplifier is disposed within the housing and connected to the speaker. A microphone is associated with the housing for detecting the exhaust noise. A control unit is disposed within the housing in communication with the microphone for receiving signals therefrom. The control unit determines an anti-noise signal for the amplifier for creating an anti-noise responsive to a detected noise source. A port dish is disposed adjacent to the acoustic outlet port which serves as a noise cancellation aid.
