Abstract

In a car (1), a sound output arrangement (5) is installed, the loudspeakers (12, 13) of which arranged in the area of the front seats (2, 3) are connected via a sound amplifier (17) and a delay arrangement (18), the delay of which can be set, and the loudspeakers (14, 15) of which arranged in the area of the rear seats (4) are connected via sound amplifiers (19) with adjustable gain, to the sound signal input (7R, 7L) of a sound reproducing device (6) of the sound output arrangement. The delay arrangements are set to a delay time (3 to 8 ms) at which there is not yet any impairment of the sound impression generated by the loudspeakers for the area of the front seats (2, 3) and the loudspeakers for the area of the rear seats and, on the other hand, the radiation level of the rear loudspeaker groups can be considerably lowered at the associated sound amplifiers (19) without impairing the sound impression in the area of the front seats. <IMAGE>
