A communications device is for transmitting acoustic signals in a motor vehicle. The communications device includes at least two transmitters and at least two receivers for transmitting and emitting acoustic signals. One transmitter and one receiver are each allocated to a spatial position. The device further includes a control unit for activating or deactivating at least the transmitters. The control unit is associated with at least one actuator element by which at least one transmitter may be selectively deactivated irrespective of a prevailing signal level.
