Abstract: An environmental sound source recognition system and an environmental sound source recognizing method thereof are disclosed. The system includes a plurality of sound sensing modules which are disposed in different planes for individually receiving a sound emitted by a target in order to obtain a plurality of sound sensing signals. A three-dimensional scanning device is used for scanning the environment to produce a three-dimensional environment image data. A signal recording module is used for recording the plurality of sound sensing signals and the three-dimensional environment image data. A processing module is used to calculate a location of the target based on the relative positions of the plurality of sound sensing modules and the plurality of sound sensing signals and to create a three-dimensional sound field according to the three-dimensional environment image data.
