多功能音乐厅的设计与声场特性分析

摘要

Based on the acoustical design of Shaanxi Normal University multifunctional Concert Hall,the two kinds of application types ＂concert hall mode＂ and ＂theater mode＂ are established.The designers adopt fine diffusion of sound field and elegant decorative art,combining with well-designed amplification system and perfect speaker system.The acoustic analysis on the scene shows that the theater has a good diffuse sound field and the sound field distribution is even.Also the analysis shows that the frequency curve of the indoor reverberation time is flat with its standard deviation ± 0.06s.The sound amplification can meet with the highest standard.So far,a great number of performances have been held here,and the results are very satisfactory.%以陕西师范大学多功能音乐厅建筑声学设计为例,建立了音乐厅与剧院声场设计模式的两种应用类型.该设计采用了良好的声场扩散和典雅的艺术装饰造型,同时结合精心设计的扩声系统和合理的扬声器系统的布置.现场声学分析表明：观众区具有良好的扩散声场,声场分布均匀;室内混响时间频率曲线比较平直,标准偏差为±0.06s;扩声系统达到音乐一级标准.举办多场高质量演出,声响效果均得到较高的评价.
