A
microphone array method for sound
source localization comprises steps of setting
spatial distribution positions of seven microphones in a seven-element stereoscopic
microphone array: s0 (0, 0, 0), s1 (d, 0, d), s2 (-d, 0, d), s3 (0, d, -d),s4 (0, -d, -d), s5 (0, 0, d), s6 (0, 0, -d), wherein, s0 is the
microphone at the origin, s1-s6 are 6 microphones distributed at other positions rather than the origin, and d is the distance from s1- s6 to the coordinate axis; establishing a
mathematical model for the
microphone array according to the
spatial distribution positions of the seven microphones; solving the
mathematical model and determining the location of the sound source. The
microphone array method for sound
source localization can effectively improve the
ranging performance on the basis of keeping the array size and the number of microphones unchanged and not sacrificing the positioning performances of the
pitch angle and the
direction angle. The array formation has a better good effect on the positioning of the
pitch angle and the
direction angle, so as to effectively improve the accuracy of distance positioning while keeping the advantages of high positioning accuracy at thepitch angle and the
direction angle in the spatial cross stereoscopic array.
