Abstract

Currently, there are fewer microphone position estimation methods and only position estimates are made for a planar microphone array. Aiming at this problem, this paper proposed a spatial microphone positioning method based on sound source array. The method arranged four sound sources in the form of a regular tetrahedron. While using its symmetry to ensure the omnidirectionality of the positioning, the distance between the microphone and each sound source was calculated according to the ranging method of the time delay estimation. The microphone position coordinates were then determined based on the geometric relationship to realize the spatial microphone position estimation based on the sound source array for online positioning. The experimental results verify the feasibility and effectiveness of the proposed method by MATLAB simulation experiment.
