This article mainly is to use a microphone array and time delay estimation of sound source localization method for sound source localization.Firstly introduces several common methods and their respective advantages and disadvantages of beam former, on the basis of the research of sound source localization based on time delay estimation method (GCC), to compare the difference in orientation of far field and near field and far field method in this paper, we study the method is determined.Due to the far field orientation, only need to measure sound signals to reach the time delay of various microphone arrays (TDOA), the rest is simple mathematical formulas are derived.Due to the small amount of calculation, this method is easy to implement, the advantages of more extensive practical application. Key words: the microphone array, sound source localizatio
