ABSTRACT:
An exemplary method for locating sound sources is disclosed. The method includes the steps of: loading a sound source location program into a handheld device; activating the sound source location program; calculating a total voltage representing sound waves received by a microphone array via a waveform computation algorithm; calculating energy intensities of the total voltage according to the total voltage; and selecting a maximum energy intensity from the calculated energy intensities, and determining the location of the maximum energy intensity, the location of the maximum energy intensity is the location of the sound source. A related system is also disclosed.
