Abstract: The present invention discloses a system for visualizing sound source energy distribution and a method thereof, wherein a propagation matrix and a window matrix are obtained firstly; next, an inverse operation of the propagation matrix is performed; next, a multiplication operation of the result of the inverse operation and the window matrix is performed; next, the result of the multiplication operation is transformed from the time domain to the frequency domain; thus, a sound source energy distribution reconstructor is established; then, an array of microphones is used to receive the sound source signals; next, a multi-channel capture device transforms the received sound source signals into digital sound source signals; lastly, a convolution operation is performed on the digital sound source signals and the sound source energy distribution reconstructor to obtain a visualized sound source energy distribution.
