摘要：

为克服疏散指示标志仅依赖视觉信息的局限性，引入基于音频信息的声音导向技术，作为疏散指示标志的有效补充。介绍声音导向技术的工作原理，建立声音定位实验系统,开展实验研究，并分析声音导向装置与音频类报警设施的兼容性,测试声音导向疏散装置定位准确率。研究表明，声音导向装置可与音频报警装置同时工作，能够在紧急疏散时明显降低疏散时间，帮助人们快速找到正确的疏散通道及安全出口。

Abstract:

In order to overcome the limitation that evacuation signs rely on visual information only, sound guidance technology based on audio information was introduced as an effective supplement to evacuation signs. The working principle of sound guidance technology was introduced, sound localization experimental system was established and experimental research was carried out. The compatibility of sound guiding device and audio alarm equipment was analyzed. The positioning accuracy of sound guided evacuation device was tested. The results showed that the sound guide device can work with the audio alarm device at the same time, and can reduce the evacuation time obviously. It's helpful for finding the right evacuation passage and safe exit quickly.  

Key words: emergency evacuation, directional sound technology;positioning accuracy, broadband sound
