摘要

基于麦克风阵列的听觉定位技术在通信和语音处理领域得到了广泛的应用。从声音传播的基本原理出发，推导出声音传播的精确近场模型。将该模型与子空间算法思想相结合，提出了一种适用于近场宽带语音信号的二维听觉定位算法，并以此构建了基于DSP的听觉定位硬件系统的开发平台。结果表明，该算法具有较好的定位效果。

Study on Auditory Localization System Based on Microphone Array

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.
