Abstract
The present disclosure provides a system for the synthesis of external sound of a vehicle, the system comprising a hazard analysis unit configured to detect a collision hazard between the vehicle and at least one further road user, in particular an outside traffic participant; at least one electroacoustic transducer; and a sound processing unit configured to generate an audio signal representing an, in particular vehicle dependent, synthetic noise signal and to control the at least one electroacoustic transducer to output a synthetic external sound based on the audio signal, wherein the sound processing unit is configured to modify the audio signal to enhance the perceptibility of the synthetic external sound by the further road user upon detection of the collision hazard.
