Device and method for driving a sound system and sound system

摘要

A driving device for a sound system by loudspeaker signals, wherein the sound system has a wave field synthesis loudspeaker array and one or several supply loudspeakers arranged separate from the wave field synthesis array includes an audio input for receiving at least one audio signal from at least one sound source, a position input for receiving information on a position of the sound source, a wave field synthesis unit for calculating loudspeaker signals for the loudspeakers of the wave field synthesis loudspeaker array, and a provider for providing the loudspeaker signal for the one or the several supply loudspeakers. The driving device enables a sound system by means of which sound localization becomes possible for the audience and at the same time pleasant levels can be achieved also in the first rows of the audience.

1. A method for driving a sound system by loudspeaker signals, the sound system comprising a wave field synthesis loudspeaker array and one or several supply loudspeakers arranged separate from the wave field synthesis loudspeaker array, the method comprising:
receiving at least one audio signal from at least one sound source; receiving information on a position of a sound source of the at least one sound source; providing one or more first loudspeaker signals for supply loudspeakers of the one or several supply loudspeakers based on an audio signal of the at least one audio signal, calculating second loudspeaker signals for array loudspeakers of the wave field synthesis loudspeaker array based on the position of the sound source, based on the audio signal and based on a position of the array loudspeakers so that a sound field produced by the array loudspeakers allows localizing the sound source by a listener in a space supplied by the supply loudspeakers; wherein the sound system is arranged in a space comprising a front edge and a left edge and a right edge, wherein there are at least two supply loudspeakers, of which one is arranged at the left edge and one is arranged at the right edge, wherein the array loudspeakers are arranged at the front edge, wherein the space comprises a stage, and wherein the array loudspeakers are installed at a front edge of the stage at or above the height of the heads of an audience in the space to be provided with sound.
