ABSTRACT:
The invention describes a method of determining the distance (d12) between two loudspeakers (L1, L2), 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 (L1). The combined signal (SN) is detected by a detecting means (M2) associated with the second loudspeaker (L2) and processed to obtain an acoustic impulse response (IR), which is used to determine the distance (d1,2) between the first loudspeaker (L1) and the second loudspeaker (L2). The invention further describes a system (1) for determining the distance (d1,2) between two loudspeakers (L1, L2) and an acoustic sound system, comprising a number of loudspeakers (L1, L2, . . . , Lk) for reproduction of multi-channel sound, and a system (1) for determining the distances (d1,2, d2,3, . . . , dk-i,k) between the loudspeakers (L1, L2, . . . , Lk) in order to automatically configure the loudspeakers (L1, L2, . . . , Lk) for that acoustic sound system.
