Abstract: In a system and a method for locating a mobile noise source, a sound sensing device catches a sound wave of the mobile noise source, and generates and stores a current sound characteristic information corresponding to the sound wave. An image pickup device catches an image of the mobile noise source, and generates and stores an entry of current image data corresponding to the mobile noise source. A spectrogram and image database stores entries of default spectrogram data and entries of default image data. An information processing unit compares the current sound characteristic information with the entries of default spectrogram data, and stores and associates the current sound characteristic information with the mobile noise source in the spectrogram and image database if no similarity between the current sound characteristic information and the entries of default spectrogram data reaches a preset value.

Abstract: In a system for locating a mobile noise source, a sound sensing device catches a sound wave of a mobile noise source within a specified area for a specified time period, and outputs a characteristic information corresponding to the sound wave. An audio comparing device in communication with the sound sensing device compares the characteristic information with a set of standard data, and outputs an activating signal in response to a specific compared result. An image pickup device in communication with the audio comparing device performs an image pickup operation to catch an image of the mobile noise source in response to the activating signal.
