Abstract
A method and an arrangement for reproducing a stereophonic or multi-channel audio signal in a space, particularly in the passenger compartment of a motor vehicle, is described Loudspeakers for reproducing acoustic signals are arranged at a plurality of positions in the space, and an amplitude and phase of the acoustic signals radiated from each loudspeaker are influenced so that wave fronts of the acoustic signals radiated by the loudspeakers overlap to form at least one first resulting wave front for a left channel and a second resulting wave front for a right channel of the stereophonic audio signal, so that the resulting wave fronts intersect in a listening zone within the space, and yield a stereo aural impression inside the listening zone.
