Abstract

A system and a method are configured to generate a sound wave field around a listening position in a room in which a loudspeaker array of K ¥ 1 groups of loudspeakers, with each group of loudspeakers having at least one loudspeaker, is disposed around a listening position, and a microphone array of M ¥ 1 groups of microphones, with each group of microphones having at least one microphone, is disposed at the listening position. The system and a method include equalizing filtering with controllable transfer functions in signal paths upstream of the K groups of loudspeakers and downstream of an input signal path, and controlling with equalization control signals of the controllable transfer functions for equalizing filtering according to an adaptive control algorithm based on error signals from the K groups of microphones and an input signal on the input signal path. At least one of the K groups of loudspeakers is operated at a distance of less than 0.5 meters from the listening position.
