The invention describes a method of determining the distance (d<SUB>12</SUB>) between two loudspeakers (L<SUB>1</SUB>, L<SUB>2</SUB>), wherein the method comprises the steps of providing a test signal (N), combining the test signal (N) with a sound signal (S) to give a combined signal (SN) in which the test signal is imperceptible to a listener (4), and issuing the combined signal (SN) by means of a first loudspeaker (L<SUB>1</SUB>). The combined signal (SN) is detected by a detecting means (M<SUB>2</SUB>) associated with the second loudspeaker (L<SUB>2</SUB>) and processed to obtain an acoustic impulse response (IR), which is used to determine the distance (d<SUB>1,2</SUB>) between the first loudspeaker (L<SUB>1</SUB>) and the second loudspeaker (L<SUB>2</SUB>). The invention further describes a system (1) for determining the distance (d<SUB>1,2</SUB>) between two loudspeakers (L<SUB>1</SUB>, L<SUB>2</SUB>) and an acoustic sound system, comprising a number of loudspeakers (L<SUB>1</SUB>, L<SUB>2</SUB>, ..., L<SUB>k</SUB>) for reproduction of multi-channel sound, and a system (1) for determining the distances (d <SUB>1,2</SUB>, d <SUB>2,3</SUB>, ... d <SUB>k-i,k</SUB>) between the loudspeakers (L<SUB>1</SUB>, L<SUB>2</SUB>, ..., L<SUB>k</SUB>) in order to automatically configure the loudspeakers (L<SUB>1</SUB>, L<SUB>2</SUB>, ..., L<SUB>k</SUB>) for that acoustic sound system. |
