Abstract
A method for visualizing sound source energy distribution in an echoic environment comprises steps: arranging in an echoic environment a plurality of arrayed sound pickup units, wherein each sound pickup unit includes at least two microphones separated by a directive distance enabling the sound pickup unit to have a primary pickup direction; disposing the sound pickup units with the primary pickup directions thereof pointing toward a sound source in the echoic environment, and measuring the sound source by the sound pickup units to obtain a sound source-related parameter; substituting the directive distance and the parameter into an algorithm to make the parameter have directivity; and then substituting the parameter into an ESM algorithm to establish a sound source energy distribution profile. Thereby, the method can measure a sound source in a specified direction in an echoic environment and establish a visualized sound source energy distribution profile.
