摘要
依据马大猷教授的微穿孔板基本理论,在对微穿孔板吸声结构完成吸声理论计算的基础上,进行参数选择并设计了微穿孔吸声反射板的结构,用于新建的阶梯教室和体育馆中.同时,分析了这种微穿孔吸声反射板结构在阶梯教室中的声反射和声吸收性能.经现场测试与主观评价,证明了此方法对阶梯教室和体育馆音质效果控制的有效性和可行性.
Based on MAA Dab-You＇ s general theory of micro-perforated panel absorbers, the theoretical results of sound absorption coefficient of the miero-perforated panel absorber structure are selected and are applied to the acoustical designs of newly-built an,phitheatre and gynmasium. Then, the sound reflection and absorption characteristics of the micro-perforated structure in the newly-built amphitheatre are investigated. The results of field testing and subjective assessment show that the proposed method is effective and feasible in the controlling of acoustics for amphitheatre and gynmasium.
