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.

Method for operating an arrangement of sound transducers according to the wave field synthesis principle

One example provides a decentrally structured apparatus including sound transducers and operating according to wave field synthesis principles. The decentrally structured apparatus includes a plurality of assembly units, each including several sound transducers, wherein the decentrally structured apparatus is configured to use a model-based approach to carry out a synthesis of wave fronts within each assembly unit for sound transducers of the respective assembly unit using audio signals and associated data for their form, and to actuate the sound transducers of the respective assembly unit with actuation signals corresponding to the synthesis.
