Abstract: In the method of adjusting the transmission of an electric signal, applied to an input terminal (1, 1'), via two transducer devices (8, 9), to an acoustic signal at two positions (P.sub.1, P.sub.2) in a space (10), (a) the levels of the electric signals applied to the two transducer devices are adjusted in such a way that the two transducer devices provide substantially equal contributions to the acoustic signal at the first position (P.sub.1), (b) the second filter unit (4) is adjusted so as to obtain a desired frequency-response characteristic (50, FIG. 5) for the transmission from the input terminal (1, 1') to the second listening position (P.sub.2), (c) the first filter unit (3) is adjusted so as to obtain a desired frequency-response characteristic (50, FIG. 5) for the transmission from the input terminal (1, 1') to the first listening position (P.sub.1). Also described are an arrangement for carrying out the method (FIG.
