Sound sensor array is composed by certain sound sensors. Compared with a single sound sensor, it can improve SNR. It has strong space selective and is available to sound signal without moving. At the same time, it can realize the self-adaptive detection, localization and tracking of sound source in a certain range, which makes it have wide application in many areas. How to blend the audio data from each node to achieve the accurate positioning and tracking is a hot study at present. This paper uses TI's MSP430F149 MCU as the control core of the sound sensor array spatial positioning system, selects a buzzer as the sound source. Different receiving points which on the space coordinate system collects sound signals to amplify and filter. According to the processed signal, MCU applies the positioning theory based on delay to form space coordinate localization algorithm and locate the sound source. The realization method is simple and test results indicate the position of high precision., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=声源定位技术在视频会议、语音识别、目标定位和助听装置等领域有着重要的应用。声音传感器阵列相比单个声音传感器来说，除了可以提高信噪比外，还能够实现声源的定位和跟踪。本文采用TI MSP430F149单片机为声音传感器阵列空间定位系统的控制核心，选择蜂鸣器为声源，空间坐标系上的各接收器对采集到的声音信号进行放大和滤波处理，单片机控制器根据各接收器处理后的信号，运用基于时延的定位理论形成空间坐标系定位算法，定位声源。, authors=^{崔燕南，刘永康，李开良，朱松盛，王 伟}, authorsList=崔燕南;刘永康;李开良;朱松盛;王 伟,
