The prototype system considers the geometry of the building, the position of the source and receiver, and the acoustic properties of the sound transmission (the sound absorption coefficient of the walls and the temperature of the environment). The system then builds the beam tree by beam tracing, and finds all possible paths of the transmission and reflection. All sound paths are then traced to compute the sound obtained by the receiver.

本系统利用建筑物的几何空间、音源与接收者的资讯，考虑建筑材料的吸音系数、环境的温度等声学相关属性，使用光束追踪法建立光束树，寻找各种可能的穿透与反射路径，建立声音的路径模型，并且计算声音的衰减，处理声音的音响输出，来模拟接收者所听到的声音与回响。

The phenomenon has been significant since the release of broadcasting channel in 1993. The impression of " Watching the World from Taipei " positioned the value of anchor stars. The famous talking shows or comment programs in BCC , UFO Network, NEWS 98, ET FM Network demonstrate feedback and performance by means of live call-in/call-out mode.

从台北看世界的既定印象主导了明星主持人的价值，中广流行网、飞碟电台、NEWS98、ET FM联播网等电台的名牌谈话性节目、评论性节目几乎可谓以台北观点出发，透过call in/callout直播互动形式，广纳专家与听众意见，形成舆论、造成回响，同时也缔造该节目或电台的高收听率佳绩。
