Active Noise Control


Low- frequency noise levels can be reduced if a counter-phase wave is added at the listener location. When noise has to be cancelled at multiple listening points, multichannel systems are needed to generate the proper signals. Consequently, advanced signal processing algorithms have to be carefully designed to assure listeners perceive a lower and, possibly, less annoying noise.
Applications: Car engine noise, airplane, car and train interior noises.
