Abstract :
Sound source localization, as a hot topic of acoustics research, plays an important role in many applications of military and civilian. The design of sound source localization system based on FPGA introduced in this thesis takes EP3C25Q240C8 as the core hardware platform. Cooperating with the external microphone array and signal collect circuit, the real-time sound signals are collected. And when there is some sound within a certain range, the system will prompt the LED and display the coordinates of the sound´s location on the LCD. The results prove the design reasonable.
