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.

Claims

1. A system for locating a mobile noise source, comprising:

a sound sensing device catching a sound wave of a mobile noise source within a specified area for a specified time period, and outputting a characteristic information corresponding to the sound wave;

an audio comparing device in communication with the sound sensing device, comparing the characteristic information with a set of standard data, and outputting an activating signal in response to a specific compared result; and

an image pickup device in communication with the audio comparing device, performing an image pickup operation to catch an image of the mobile noise source in response to the activating signal.

2. The system according to claim 1, wherein the characteristic information includes a maximum of an amplitude of the sound wave.

3. The system according to claim 1, wherein the characteristic information includes a spectrogram data of the sound wave.

4. The system according to claim 1, wherein the characteristic information includes both a spectrogram data of the sound wave and a maximum of an amplitude of the sound wave.

5. The system according to claim 1, wherein the set of standard data includes a maximal amplitude database and/or a spectrogram database of all the mobile noise sources to be monitored.

6. The system according to claim 1, wherein the image pickup device is a digital still camera, a video camera or a combination thereof.

7. The system according to claim 1, further comprising a video comparing device in communication with the audio comparing device, comparing an image data of the mobile noise source with a default image data corresponding to the mobile noise source, and issuing a confirming signal in response to a specific compared result.

8. A method for locating a mobile noise source, comprising:

transforming a sound wave received in a specified area for a specified time period into a characteristic information;

automatically issuing an activating signal when a compared result of the characteristic information and a default audio data shows a status to be noted; and

automatically picking up an image of the mobile noise source and generating and storing an image data of the mobile noise source in response to the activating signal.

9. The method according to claim 8, further comprising automatically issuing a confirmation signal when a compared result of the image data with a default video data confirms the status to be noted.

10. The method according to claim 8, wherein the characteristic information includes a maximum of an amplitude of the sound wave.

11. The method according to claim 8, wherein the characteristic information includes a spectrogram data of the sound wave.

12. The method according to claim 8, wherein the characteristic information includes both a spectrogram data of the sound wave and a maximum of an amplitude of the sound wave.

13. The method according to claim 8, wherein the set of standard data includes a maximal amplitude database and/or a spectrogram database of all the mobile noise sources to be monitored.

14. The method according to claim 8, wherein the image data is a still image, a video film or a combination thereof.
