摘要
穹幕展演空间因其视觉效果越来越受到建筑师和业主方的青睐,但这种空间在声学上有一些缺陷,利用CATT声学模拟软件对一种特定的穹幕空间进行声学分析,可以发现单单运用传统的声学计算方法无法发现典型声学参数的分布规律,而计算机声学模拟分析能及早地发现这些潜在声学问题,并且能半定量地解决一大部分的问题,是值得推广的一种技术手段。
More and more architects and owners incorporate arciform movies into dome spaces because of the magnificent scenes,but acoustically there are some imperfections exist in such spaces. Traditional acoustical calculation is unable to discover the distributions of specific acoustical parameters in dome spaces,but computer simulation software can. using CATT-Acoustics to analyse one dome theater,some potential problems were found and solved with semi-quantitative way.With this regard,it is worthy of promoting simulation technical means to deal with room acoustics problem in dome spaces.
