In this work, a design methodology was developed and a working piezoceramic based active control system for the problem of noise reduction of machinery was demonstrated. Design methodologies included ...

Active noise control helps cut down the noise in a vehicle’s cabin. The challenge, though, is creating an ANC system that reduces road noise with fewer components.

Different methods of passive and active noise isolation and noise cancellation, or combinations of the two types, can be applied to help defeat the noise that plagues most all electronic systems.
