空间吸声体的设计与应用

文章总结了三十多年来同济大学声学所在空间吸声体方面的研究和工程实践经验。对常用的三种形式—平板式、立体式和圆管式空间吸声体，以及它们的不同布置方式的吸声效果和性能价格比作了分析，所得结果可为设计提供指南。文中还介绍了除纤维性材料以外的其它多种选择，以适应多方面的需要。文中以实例显示其别致多样的造型，丰富了室内艺术效果。

Design and application of functional absorbers

This paper gives an overview of our research and practical experiences on functional absorbers over the past three decades. Analysis of the absorption characteristics of three different geometrical forms of functional absorbers, i.e., the panel, the cubic and the tubular, applied with different arrangements, and the resulting esthetical effects are also presented in this paper. Several non-fibrous materials are used for functional absorbers with special features, both in acoustics and architectural appearance.
