1. A system for locating a mobile noise source, comprising:
- a sound sensing device catching a sound wave of a specified mobile noise source within a specified area for a specified time period, and outputting a characteristic information corresponding to the sound wave, wherein the characteristic information includes a spectrogram data of the sound wave;
an audio comparing device in communication with the sound sensing device, comparing the spectrogram data of the sound wave with spectrogram data of a plurality of mobile noise sources contained in a database, and outputting an activating signal if the spectrogram data does not match with any of the spectrogram data in the database; and
an image pickup device in communication with the audio comparing device, performing an image pickup operation to catch an image of the specified mobile noise source in response to the activating signal.

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.

5. A method for locating a mobile noise source, comprising:
-
transforming a sound wave received from a specified mobile noise source in a specified area for a specified time period into a characteristic information, wherein the characteristic information includes a spectrogram data of the sound wave; automatically issuing an activating signal when a compared result of the spectrogram data of the sound wave with spectrogram data of a plurality of mobile noise sources contained in a database, indicates a mismatching status; and automatically picking up an image of the specified mobile noise source and generating and storing an image data of the specified mobile noise source in response to the activating signal. - View Dependent Claims (6, 7, 8)
