基于麦克风阵列的声源定位模型构建

Sound Source Localization Model Based on Microphone Array

本文设计了一种基于广义互相关时延估计的麦克风阵列的声源定位算法,在建立麦克风阵列时,通过对不同麦克风模型的实验进行研究,最终选定了X阵列的麦克风阵列作为算法模型来定位声源,并建立合适的空间坐标系来准确地确定在大厅中走动的人的位置。本文的声源定位模型算法是建立在远场模型且排除外界干扰的假设上。本文的创新点在于对解决定位人位置的问题上的算法中采用广义互相关时延估计算法,其优势在于原理简单、运算量小且对混响和抗噪声能力较强。

In this paper,we design a microphone array sound source localization algorithm based on the generalized cross-correlation time-delay estimation.When building the microphone array,we study different models of different microphone numbers,and finally select the microphone array of X array as the algorithm model to locate the sound source,and establish the appropriate space coordinate system to accurately determine the position of people walking in the hall Set.The algorithm of sound source location model in this paper is based on the assumption of far-field model and excluding external interference.The innovation of this paper is that the generalized cross-correlation time delay estimation algorithm is used in the algorithm to solve the problem of locating human position.Its advantages are simple principle,small amount of calculation and strong ability to resist reverberation and noise.
