体育馆建筑就其形式可分为宏观形式(体形)和微观形式(内部构造)。传统的体育馆外形多采用矩形、多边形等,这样长期的重复出现给人一种呆板、单调的感觉。建筑师为了增强体育建筑的亲和力、美化周围环境和装扮城市,纷纷尝试,创造了形体各异的建筑设计,尤其是新材料、新设备,新技术的发展使建筑师们的设想变成了现实。在十一届亚运会体育馆的设计方案中,椭圆形的朝阳体育馆和三角形的石景山体育馆,以其新颖的建筑构思和独特的造型获得好评。但是,从几何声学角度来看,这两种建筑体形都有明显的声学缺陷,是两馆的短处,因此,如何扬长(保持和发扬 Gymnasium architecture can be divided into macro form (body shape) and micro form (internal structure). The shape of traditional gymnasiums uses rectangles, polygons, etc., so that long-term repeated appearances give people a dull, monotonous feeling. In order to enhance the affinity of sports buildings, beautify the surrounding environment and dress up the city, architects have tried to create architectural designs with various shapes, especially new materials and new equipment. The development of new technologies has made the architects’ visions a reality. . In the design plan for the 11th Asian Games Gymnasium, the oval Chaoyang Stadium and the triangular Shijingshan Stadium have been well received for their novel architectural ideas and unique shapes. However, from the point of view of geometric acoustics, these two types of buildings have obvious acoustic defects, which are the weaknesses of the two museums. Therefore, how to grow (maintain and promote)
