摘要： The invention relates to a system for generating sound waves for at least two separate zones of a single space. The system includes, for each zone of said space: at least one array of high-frequency loudspeakers forming a directional sound wave; and at least one low-frequency loudspeaker. The system also comprises means for audio processing of the signals transmitted to the loudspeakers, which means control at least one loudspeaker to generate destructive sound waves in at least one zone of said space and to obtain distinct sound contents in said at least two distinct zones of said space. To do this, the audio-processing means control each low-frequency loudspeaker individually and each array of high-frequency loudspeaker mutually in order to generate the destructive sound waves.
