体育馆声学吸声材料设计与应用

发布日期:2020-07-11 作者: 点击:

按照(体育馆声学设计及测量规程》规定,确定满声为500Hz~1000Hz,混响时间为1.5。当容积确定后,决定混响时间的因素为吸声系数,而吸声系数的大小则是由所采用的吸声材料所决定的。体育馆墙壁、网架都安装有吸声材料,舞台、大厅上的声波到达墙壁后,通过吸声材料将其吸收以减少声波的反射。体育馆 除了对内部的吸声材料要求较高外,其内部几何形状和结构设计也有较高要求。若在墙壁上安装了吸声材料,却未注意其几何形状的设计,同样会使舞台上的直达声产生回声等缺陷,使声音的质量变差。因此对其进行的吸声材料的设计和安装是建筑声学设计的重要工作。如何正确地使用吸声材料,消除不需要的噪声,控制最佳的混响时 间,在体育馆设计方案时,必须了解建筑材料及建筑结构的声学特性,合理设计、使用和安装,才能保证大厅内的每一 个观众都能听到完美的声音。
