Sound source detection device, especially for use in a motor vehicle driver assistance system, detects phase displacements or signal time of flight differences from sound sources that are detected using multiple microphones

Device for detecting external sound sources in the surroundings of a motor vehicle comprises a non-linear microphone array and an evaluation unit that can determine the position of sound sources from the relative phase displacements of the sound sources to each of the microphones and or sound signal...
