METHOD FOR OPERATING AN ARRANGEMENT OF SOUND TRANSDUCERS ACCORDING TO THE WAVE FIELD SYNTHESIS PRINCIPLE

摘要

A method and a device for operating an arrangement of sound transducers according to the wave-field synthesis principle. In order to supply an extended audience region with the same signal, the same signal content is generated by at least two virtual sound sources, which are arranged such that the wavefronts thereof are directed only onto a part audience area, rather than generating only a single beam extending over the entire audience area. The wavefronts of the distributed virtual sound sources add up vectorially in the plane of the arrangement of sound transducers, whereby the effectiveness of the sound generation is increased.

1. A method for operating an arrangement of sound transducers according to the wave field synthesis principle to supply an audience area with an audio signal content, the method comprising:
providing the arrangement of sound transducers; and operating the arrangement of sound transducers in such a manner that the arrangement of sound transducers radiates wave fronts toward the audience area, the radiated wave fronts corresponding to wave fronts of the same audio signal content that are generated in a model by at least two virtual sound sources, which are arranged behind the arrangement of sound transducers from the point of view of the audience area, and which direct the respective wave fronts of the same audio signal content only at a part of the audience area.
