Abstract
A repetitive noise cancellation system for multiple noise sources employing a controller (36) which senses radiated noise by reference sensors (35) and the status of the noise sources by position sensors (37, 38) and automatically controls one of the noise sources so that the noises being emitted from the multiple sources cancel one another.
