Noise-reduction in aircraft

Abstract:

Systems and methods for performing noise reduction in a vehicle comprising a noise reduction system and a plurality of zones are herein provided. A noise reduction criterion for the vehicle is obtained. A first one of the plurality of zones for which noise reduction is to be performed is determined, based on the noise reduction criterion. The noise-reduction system is controlled to perform noise reduction in the first zone, wherein performing noise reduction in the first zone causes the noise reduction system to effect a resultant adjustment in noise level in at least a second one of the plurality of zones.
