Abstract

The invention relates to a device and method for reducing noise, in indoor and outdoor areas, from multiple unwanted sound sources or from a single mobile noise source. The device is a set of loudspeakers that consists of multiple panels assembled together in a geometric configuration that depends on the coverage angle of the loudspeakers used. The device implements an active signal-processing method which consists of an estimator of the equivalent noise source, an adaptive phase shifting and correction unit, and a loudspeaker control unit, which synthesises the sound.
