A method for providing sound tracking information includes detecting a sound occurred adjacent to a subject vehicle and generating a sound tracking result based at least on sound data regarding detected sound, determining a detect on category as one of a non-vehicle detection, an error detection or a vehicle detection, based at least on the sound tracking result, and determining an error detection index adjusted based at least on the detection category as well as whether a notification based at least on the detection category is generated. Herein, the sound tracking result includes a probability of whether there is at least one other vehicle at each of a plurality of angles in each of a plurality of frames continued according to time.
