教室声学设计分析

The Analysis of Classroom Acoustics Design

对两种不同类型教室的房间比例、混响时间、频率响应、本底噪声等建声参量分别进行了实际测量和计算。利用有限元模型模拟的方法给出了部分声场分析。比较了两教室设计中出现的问题并进行了讨论进而明确了教室声学设计的基本要素,为教学用房的建筑设计提供了较为合理的参考。

The acoustic qualities including room ratio,reverberation time,frequency response and background noise level were measured and calculated in two type classrooms. The numerical analysis of sound field was given by using Finite element method. The problems occurred in designing of two classrooms were discussed and the acoustic requirements of classroom design were proposed. The results obtained are hopefully valuable in educational building design.
