TDE-Based 2D Real Time High Accuracy Sound Source Location Calculation Using a Special Microphones Arrangement
The most important issue in the cross correlation based localization methods is the measuring of time delay between the signals received by the microphones. Using these methods, high accuracy sound source localization needs highly accurate time delay measurement, and therefore, high frequency sound signal sampling rates. Moreover, the need to use numerical analysis methods for local calculations will increase computation time and also the cakulations may not converge. In this paper, a simple and fast location calculation method for TDE-based 2D accurate localization of sound sources in open environment and long distances is proposed. Based on the proposed method, a special microphone arrangement is implemented. Experimental results show that the proposed method has more accuracy and less processing time for localization in com parison with previous methods.
