Abstract Machine intelligence requires convenient and effective estimation mode for sound localization. According to the tight relation of Head Related Transfer Function (HRTF) and location, this paper studies a sound localization method based on HRTF. Using the forward neural network, the direction information is extracted and multi coded in parallel, and then is weighted to estimate the sound position. Simulations show that the method is more accurate and compact. Finally, robust analysis is given to prove validity of simulation results.
