Science and technology change with each passing day in recent years. The interface needs more accurate and convenient between machine and people, one of them used the microphone that respond to location of the sound source. This research used Microphone array to find the TDOA of sound source localization on Cross Correlation function. There are two methods of sound source localization. First kind of method is using TDOA on hyperbola. The other is using TDOA on neural network. The research perform simulation with MATLAB. Based on the simulation results ,the prove the feasibility of the research. And offer a reference of technical research in the future.
