铝合金穿孔吊顶板的吸声性能研究

Aluminum alloy perforation ceiling board sound absorption performance research

铝合金穿孔吊顶板是当代建筑中的重要的吊顶和装饰材料,同时由于其具有较好的吸声性能,在计算机机房,高级宾馆,大型商场,会展大厅,候机楼,地铁车站等建筑中被广泛的使用。因此对铝合金穿孔吊顶板的吸声性能的研究显得尤为重要。本文首先介绍了一种全新的吸声结构,并且在不同的条件下分析了铝合金穿孔吊顶板的吸声性能。进一步对吸声峰值的频率进行了计算,测量结果和计算值吻合的较好,对改善铝合金穿孔吊顶板的吸声性能提供了数据上的支撑。

Aluminum perforated ceiling board is an important the condole top of contemporary architecture and decoration materials,due to its good sound absorption performance at the same time,in the computer room,senior hotels,shopping malls,exhibition hall,terminals,subway stations,has been widely used in construction.So on sound absorption properties of aluminum perforated ceiling board research is particularly important.At first,this paper introduces a kind of brandnew acoustical structure,and analyzed under the condition of different aluminum perforated ceiling board sound absorption performance.Further was calculated,the frequency of sound absorption peak measurement results and calculated value is better,to improve the sound absorption performance of aluminum alloy perforation ceiling board provides data support.
