近年来，许多学校修建了多功能体育馆，要求能够进行体育课教学、学生业余体育训练、体育比赛、学生大会和文艺演出等活动。但由于这种体育馆的比赛大厅容积较大，平均自由程较长，混响时间过长，所以声音极其模糊，引起声聚焦、回声、多重回声等音质缺陷的机会非常多。根据现在多功能体育馆的使用要求，从理论、实践两方面可以了解到体育馆声学设计包括建声设计、电声设计两方面。

建声设计主要是考虑比赛大厅内的吸声处理，充分降低馆内的混响时间以保证厅内的语言清晰度和观众席、比赛场地不出现回声、颤动回声和声聚焦等音质缺陷。对于体育馆的比赛大厅来说，能够做吸声处理的范围较少，尤其是侧墙，大部分被看台和侧窗占用，所以要求体育馆吸音板新疆25选7走势图这些吸声材料、吸声结构必须有较高的吸声性能。

分析了近几年常用的几种空间吸声体的吸声原理和吸声性能，可以利用有限的材料和空间获得最理想的声场效果。
