Abstract
The precise near field model of sound transmission was deduced.Generalized Cross Correlation(GCC) algorithm based on Phase Transform(PHAT) was adopted to estimate time-delay,and a time-delay selection algorithm based on data relation was also put forward.Then the time difference of arrival algorithm was used for sound source localization,by which the development platform was built based on the DSP auditory localization hardware system.The results show that the error of the angle estimate is less than 3° in near field model of sound transmission.
