Abstract:	到達時間差（TDOA）是一種因其簡單性和準確性而被廣泛用於聲源跟踪的方法。此外，該研究將使用基於其TDOA的圓形麥克風陣列進行聲源跟踪。麥克風陣列中較高靈敏度的寬頻率響應使其在聲源跟踪研究中廣受歡迎。有許多方法可以獲得TDOA，。因此，本研究提出了從其TDOA獲得到達方向（DOA）的GCC方法，然後使用三角形三角技術從其獲得的DOA和兩個麥克風陣列之間的距離測量源位置。;Time Difference of Arrival (TDOA) is a method that has been widely used for sound source tracking because of its simplicity and accuracy. Moreover, this research will do the sound source tracking using a circular microphone array based on its TDOA. The higher sensitivity wide range of frequency response in microphone array make it popular among sound source tracking research. So this research proposed the GCC method for obtaining the Direction of arrival (DOA) from its TDOA and then measure the source position using triangle trigonometry technique from its obtained DOA and the distance between two microphone array.
