摘要
由于空间吸声体在声场中暴露的面积大，提高了单位面积的吸声性能，从而有可能用最小的吸声处理面积而获得较大的吸声量。是一种经济、有效和便于施工的吸声构造。目前被广泛用于控制噪声和厅堂内的混响时间。本文概述空间吸声体的吸声机理、计算方法、设计中应注意的问题，以及在各类工程设计中的应用和今后的发展趋势。
For the exposed area of spatial sound absorbent in sound field is large and taises the sound absorption performance per unit area, it is possible to minimize the area for sound absorption treatment and gain better sound absorption effect. It is a sound absorption form that is econondcal, effective and easy to construct, and used widely to control noise and reverberation time in halls nowadays. The article oudines the important questions of sound absorption mechanism, calculating, and designing for spatial sound absorbent, as well as its application in various project designs and development tendency in futare.
