Abstract
A method used for visualizing sound source energy distribution in reverberant environment. Firstly, arrange a plurality sound receiving units in an array in a reverberant environment, wherein the sound receiving unit includes at least two microphones spaced a directionality distance from each other such that the sound receiving unit has a primary sound receiving direction. Following, let the sound receiving unit with the primary sound receiving direction face a sound source in the reverberant environment and obtain a parameter correlated with the sound source by determining the sound source. Next, substitute the directionality distance and the parameter into an algorithm to make the parameter have directionality. Finally, substitute the parameter having the directionality into an equivalent source method to construct a sound source energy distribution. Accordingly, the method could obtain a visualized sound source energy distribution via measuring the sound source along a designated direction in the reverberant environment.
