A Robust Sound Localization Algorithm Using Coordinate Transform

This paper describes the principle of passive sound localization and sound localization algorithm based on a four-element array example discussed in the wind for positioning of the passive voice, and to amend their ways, this paper focuses on the measurement of the target signal in the delay algorithm based on simulation, and wind for passive localization impact and how to modify the impact, given the correction formula, and by computer simulation, the simulation calculated the azimuth error of the table can see, after following a marked improvement in azimuth, so as to achieve the effect of the amendments to improve the positioning accuracy.

The common localization algorithms of microphone array is based on linear array or circle array which is unblocked (there is no block between sound source and microphone). This paper we research the sound localization algorithm based on helmet-mounted microphone array which is a kind of blocked array. This paper takes the attenuation of high-frequency by helmet into account, and utilizes intensity decay of different backward microphones to construct localization algorithm. Experimental results show that the localization method of the high-frequency sound signal based on the direct path improves the accuracy of localization compared with common algorithm based on unblocked microphone array.
