摘要

The device has control units (1,3), where the unit (3) is installed in a locomotive. A special acoustic signal is selected from a group using control components that are assigned to the unit (1). The unit (3) determines the control signal that is pre-determined for the selected group and signal. The control signal represents a storage address assigned to the signal. A playback device (6) reproduces a special acoustic signal.
