摘要
目的:通过对北京市某高校的九类异形教室的混响时间测量和理论分析,研究不同长宽高之比的教室的混响时间的规律,从而为学校教学楼的声学设计提供依据。方法:实验主要应用01dBSolo声级计对某高校的九类不同类型教室的空场和满场混响时间进行测量,并通过SPSS统计软件分析测得数据,并进行回归分析。结论:九类不同长宽高之比的教室测量值并不遵循理论计算值和推荐值,其测量值呈现一定的规律,呈三次曲线(Cubic)分布。
Objective： To a university in Beijing in nine categories of special-shaped classroom reverberation time measurement and theoretical analysis,the different dimensions of the ratio of the classroom reverberation time rule,and for the teaching building acoustics design provides the basis.Methods： The experiment come to a university in nine categories of different types of the classroom were packed and reverberation time measuring with 01dBSolo sound level meter,and through the SPSS analyse measured data,and a regression analysis.Conclusion： Nine kinds of different aspect ratio of the measured value of the classroom did not follow the theoretical value and recommended value,the measured value on a kind of law,show three curve（Cubic） distribution.
