The cancellation of repetitive noise and vibration by active nethods
Abstract
The active attenuation of diesel engine noise is discussed as well as the active control of vibration. The system used is found to work best with repetitive sources of noise. Applications of active noise attentuation include noise inside helicopters and propellor aircraft, auxilliary generators and large compressors, and noise on emergency vehicles such as fire engines and snow cats.
