Abstract: A sound classification system for a vehicle includes a plurality of microelectromechanical system (MEMS) microphones disposed at the equipped vehicle and sensing sounds emanating from exterior of the equipped vehicle. A sound processor is operable to process outputs of the MEMS microphones to classify a source of sensed sounds. The sound processor processes the outputs to determine the direction and distance of the source of the sensed sounds relative to the equipped vehicle. The MEMS microphones are one of (i) incorporated in respective ones of a plurality of exterior viewing cameras of the equipped vehicle and (ii) attached at a surface of at least one window of the equipped vehicle.
