Peter Rutherford和 Deborah Withington两位博士向我们介绍了定向声音指示系统 (Directional Sound)是如何在充满烟雾的建筑物中引导人员逃生的。人类行为学的研究表明 ,面对紧急事件 ,人们往往下意识地沿着他们原先进入建筑物的路线逃生。但是这些路线大多不是最快捷或最适合 Two PhDs, Peter Rutherford and Deborah Withington, show us how Directional Sound guides people to escape in smoke-filled buildings. Human behavior studies show that in the face of an emergency, people tend to subconsciously escape along the lines that they originally entered the building. However, most of these routes are not the quickest or most suitable
