体育馆声学设计探讨

On the acoustic design of gymnasiums

本文分析了我国综合性体育馆共同的体形特征及其所导致的运用建筑本学时出现的若干问题，探讨了有关的声学标准，并以工程实践为例，说明必须依靠建筑产学设计和电声设计的结合，才能作好体育馆的声学设计．

The gymnasiums in this country are a new kind of multi-purpose halls. From the view point of acoustic design , a gymnasium has its own characteristics: sound source is located at the central large area of the hall, with acoustically highly reflective floor; the mean free path of sound is very long ; the shape and the sbe of the sport hall are decided by sport activities, building structures, etc. and thus vary. Due to these reasons, the role of architectural acoustic design is limited. On the other hand, electroacoustic techinology is under rapid development, By the use of good combination of these two means, gymnasiums can be provided with optimun acoustic conditions for both speech and music.
