Claim Text:
1. A sound system for acoustically reproducing at least two electrical audio signals and establishing at least two sound zones that are represented by individual patterns of reception sound signals, the system comprising: a signal processing arrangement that is configured to process the at least two electrical audio signals to provide processed electrical audio signals; and at least two loudspeakers that are arranged at positions separate from each other, each configured to convert the processed electrical audio signals into corresponding acoustic audio signals; wherein each of the acoustic audio signals is transferred according to a room transfer matrix from each of the loudspeakers to each of the sound zones where they contribute to the reception sound signals; processing of the at least two electrical audio signals comprises inverse filtering according to a filter matrix; and inverse filtering is configured to compensate for the room transfer matrix so that each one of the reception sound signals corresponds to one of the electrical audio.
