Abstract (en)

[origin: DE19739425A1] The invention relates to a method and a device for reproducing a stereophonic or multi-channel audiosignal in a space, especially a passenger compartment (10) of a motor vehicle. According to the invention, loudspeakers are arranged in several positions in said space for reproducing acoustic signals and the amplitude and phase of the acoustic signals emitted by each loudspeaker (1 to 7) are influenced in such a way that the wave fronts (83 to 87) of the acoustic signals emitted by said loudspeakers (1 to 7) superimpose to form a first resulting wave front for the left channel and a second resulting wave front (80) for the right channel of the stereophonic audiosignal. The resulting wave fronts intersect in an audibility zone within the space and give an impression of stereo sound within said audibility zone.
