摘　　要：在体育场馆建筑声学条件无可更改的情况下,根据在体育场馆中使用扩声系统应达到的最终目的——解决听音清晰度问题,对扩声系统的设计思想、设计方法进行了论述。根据所提出的设计思想,从体育场馆如何布置扬声器这个基本点入手,提出了以现场模拟的方法,对扬声器的布位选择、指向性角选择、投射区域测量、最大声压级确定等问题进行了定性分析。Under the unchangeable acoustic circumstance of a gymnasium or an arena, based on the ultimate purpose of the audio amplification system in such a place to solve the problem of the definition, according to that, the ideas and methods of designing an audio amplification system are discussed. Process with the discussion of how to place the loudspeakers, an on - the - spot simulation method is used in this experiment. The location where the loudspeakers are placed, the way each of them headed to, the sound covered area, and the max sound pressure level are measured and analyzed qualitatively.
