摘要
依据马大猷教授的微穿孔板基本理论,进行参数选择并设计了微穿孔吸声反射板结构,用于阶梯教室中,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的性能。
Besed on MAA Dah_You＇s general theory of microperforated panel,the theoretical result of sound absorption coefficient of the micropexforated panel absorber sturcture are selected.It is applied Io designing the controlling building acoustics in the new classroom. Sound reflecting and absorbing characteristics of the microperforated sturcture in the new leature theatre are investigated . The results of field testing and subjective assessment have showed that the fulfilling acoustical performance of the classroom have been achieved.
