SOUND SOURCE LOCATION DEVICE BASED ON BINAURAL INTENSITY DIFFERENCE

In recent years, sound source location devices have been widely used in civil, industrial, and military applications. Currently, sound source positioning devices are realized mainly by program algorithm, which has complex technology and high cost. This paper uses traditional physical methods to design a sound source positioning device based on binaural intensity difference and triangulation, mainly composed of sound sensors, a spectrometer, and an oscilloscope. Through theoretical calculation and experimental measurement analysis, the relative error of the device is less than 6%, and the device has good accuracy. The device has good expansibility, can be equipped with a motor drive system, and has the advantages of low cost and robust reproducibility.
