An acoustic support system comprising a number of mobile units each including a electronic control unit, a memory for data representing acoustic signals, a reception unit for receiving control data, a transformation unit for transforming the part of data selected by the control unit from the data stored in the memory into acoustic signals, and a sound unit for playing back the acoustic signals. Further it is provided for a central unit including a control unit for generating control data and a broadcasting unit for transmitting control data to selected mobile units. The mobile units with the acoustic signals stored therein can individually be selected and controlled to allow realistic acoustic simulation of events. The system is easy to handle and can be used repeatedly and has a low price.
