A Sound Localization Algorithm Based on Helmet-Mounted Microphone Array Using the High-Frequency Intensity Difference

Abstract:

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.
