使用麦克风阵列的声源定位和跟踪已成为室内声学，电话会议系统和声音产生对象的跟踪的关注焦点。估计源定位的当前方法取决于麦克风对之间的传统时间延迟估计技术，然而，忽略环境噪声，来自周围的反射和封闭空间中的混响。在本研究中，设计并开发了基于3D麦克风阵列的声源定位器和跟踪器（ASLT），用于实时源检测和定位。(Acoustic source localization and tracking using microphone arrays has become a focus of interest in room acoustics, teleconference systems and tracking of sound producing objects. The current methods to estimate the source localization depend on conventional time-delay estimation techniques between microphone pairs, however, ignoring the ambient noise, reflections from surrounding and reverberation in the closed space. In this study, an acoustic source localizer and tracker (ASLT) based on 3D microphone array is designed and developed for real time source detection and localization.)
