  • Active noise cancellation system, arrangement, and method
    Patent number: 7539459
    Abstract: Noise of a noise-producing object may be at least partially cancelled by a system that emits sound at a polarity substantially opposite to a polarity of detected noise and includes a member having elements disposed in the vicinity of a noise-producing object, some of the elements may be configured to emit noise, and some of the elements may be configured to detect noise and where a signal indicative of the detected noise may be received by a controller which sends a signal to cause at least some of the elements to emit sound at a polarity substantially opposite that of the detected noise, and includes an analyzer to determine when detected noise is indicative of one or more conditions of the noise producing object.
