Abstract: Stations (4) which can produce discrete, specific acoustically modulated data signals (4e) are used for selectively reproducing a sound sequence (12a) on communication units (3). The communication units (3) occupy lines (outgoing: 117b, 116b, 113; incoming lines 115, 116b, 117b) of a transmission network which connects them to a processing station (9). A data signal is recorded in the acoustic proximity region of a station (4) by the sound transducer (3a) of a communication unit (3), is forwarded to the processing station (9) and detected there. The line (117a, 116a, 113) is detected on which it was received. The processing station (9) transmits the tone sequence (12a) assigned to the data signal (4e) to the communication unit (3) via the determined line (115, 116b, 117b). Thus, the desired tone sequence (12a) is played. The detection reliability is increased by transmitting the time and content of the transmitted data signals (4e) to the processing station (9) via a separate transmission path (106, 6, 107). The interaction complexity can be increased by reporting back the interaction level to the processing station (9) of the respective station (4). The method allows station-specific location of the users. The device according to the invention for the selective recording of sound sequences consists of sound signal generating stations (4) with or without input device communication units (3) with sound transducer (3a) a transmission network and a processing point (9). In that the station (4) additionally transmits the time and content of the transmitted data signals (4e) to the processing station (9) via a separate transmission path (106, 6, 107). The interaction complexity can be increased by reporting back the interaction level to the processing station (9) of the respective station (4). The method allows station-specific location of the users.
