摘要： A technique for reducing noise in a listening environment. The technique includes dividing the listening environment into a plurality of zones, where each zone is associated with a different active noise cancellation (ANC) system. A boundary between a first zone included in the plurality of zones and a second zone included in the plurality of zones comprises open space. The technique further includes assigning a plurality of acoustic sensors and a plurality of speakers to the ANC system associated with each zone included in the plurality of zones. The technique further includes, for each zone included in the plurality of zones, acquiring acoustic data via the plurality of acoustic sensors, processing the acoustic data, via a processor, to generate noise cancellation signals, and outputting the noise cancellation signals via the plurality of speakers.

摘要： A silencing apparatus for effectively reducing noises in the three dimension space which detects physical characteristics of the noise source by the laser doppler sensor unit during the noise source comes close to the telephone booth, and collects acoustic characteristics of the noise source by the sensor microphone array. The control portion generates an inverse-phased signal against the noise source so that the noises are decreased at the error sensor, and stores the noise source information (physical characteristics and the acoustic characteristics) and the generated inverse-phased signal. When the same noise source come closely, the voice is generated from the speaker using the inverse-phased signal stored in the memory. The control potion generates an inverse-phased voice from the speaker when the collected noise by the sensor microphone is actually over a certain threshold level.
