| 铝合金穿孔条板是现代建筑中一种新型的吊顶及墙面装饰材料。而且还可以组成良好的吸声体,常用于宾馆大堂、机场候机厅、地铁车站、商场、展览大厅、计算机房等建筑。本文介绍了两种吸声结构,在五种空腔条件下的吸声特性,其中包括500mm和1000mm的大空腔。同时还分析了吸声峰值频率,其预计值和实测值基本相符。 |
| 英文摘要: |
| Perforate aluminum ceiling strips is a new decorative material of ceiling and wall in modem buildings. It also can be made into good absorber. It often used for the ceilings of hotel lobby, airport, subway station, supermarket, exhibition hall, computer room, etc.This article introduces the absorption properties of this kind of absorbing structure with five kinds of air gaps behind the absorbing layer, in which there are 500mm and 1000mm gaps. At the same time, this article analyzes absorbing peak frequency, its estimative data are in accordance with the data resulted from the experiments. |
