摘    要:基于麦克风阵列的声源定位技术在通信、语音处理等领域得到广泛的应用。从声音传播的基本原理出发,推导出了精确的声音传播的近场模型,利用该模型并结合子空间算法的思想,提出了适用于近场宽带语音信号的二维声源定位算法,并在算法模型的基础之上搭建了基于DSP的声源定位硬件系统开发平台。结果表明,该算法能够得到较好的定位效果。

关 键 词:声源定位  传声器阵列  DSP  TMS320F6713

Study on auditory localization system based on microphone array
Abstract:The auditory localization technology based on microphone array has wildly used in the field of communication as well as voice processing.Embarking from the basic principle of sound transmission,we deduce the precise near field model of sound transmission.Combining such model with the idea of subspace algorithm,we also put forward a two-dimensional auditory localization algorithm which is suitable in the near field wide band voice signal,by which built the development platform based on the DSP auditory localization hardware system.The result turns out this algorithm has an efficient localization.
Keywords:DSP  TMS320F6713
