1. A heart support system comprising:
a first control unit;
at least one first sound-generating device, said control unit configured to detect and process events including alarm events, and to process data and carry out control tasks in the heart support system;
at least one storage device, which is configured to store one or more defined alarm signal time curves and one or more alarm priorities, such that each alarm signal time curve and each alarm priority assigned to one or more defined alarm events,
at least one sound-generation controller, which is configured to, when an alarm event is detected, overlay a volume time curve onto the alarm signal time curve assigned to the alarm event in the storage device, said volume time curve based on the alarm priority assigned to the respective alarm event in the storage device and the length of time since the detection of the alarm event,
wherein the at least one sound-generation controller is configured to actuate one or more sound-generating devices upon detection of an alarm event such that the sound generating devices convert the aforementioned alarm signal time curve with the defined overlaid volume time curve into sound signals,
at least one second, electrically operated sound-generating device configured to be actuated separately from the first,
at least one second control unit, which is configured to detect a functional failure of the first sound-generating controller and to actuate the second sound-generating device such that the second sound-generating device generates defined sound signals.
