A 3D Localization Method of Multiple Acoustic Sources Based on Two L-type Microphone Array

摘要

In order to solve the problem that the traditional methods can't accurately measure the localization of multiple acoustic sources in far field, this paper presents a new multiple acoustic sources localization method using in the near field and the far field. This method use two L-shape microphone arrays, in each array obtain signal' s DOA by jointly estimating the DOA and frequencies of signals.finally，locations of multiple acoustic sources can be estimated based on DOA' s pair of two L-shape microphone array. The simulation examples indicate the method in the near field and the far field all can be accurately measured locations of multiple sound sources. By adjusting the distance between two Lshape microphone arrays can be obtained standard deviation below 5% acoustic localization accuracy.
