景音空间吸声体与室内表面上的吸声材料相比，在同样投影面积下，景音空间吸声体具有较高的吸声效率。这是由于空间吸声体具有更大的有效吸声面积（包括空间吸声体的上顶面、下底面和侧面）；另外，由于声波在吸声体的上顶面和建筑物顶面之间多次反射，从而被多次吸收，使吸声量增加，提高了吸声效率。通常以中、高频段吸声效率的提高最为显著。

　 景音空间吸声体的悬挂数量应根据吸声体的吸声特性和降低室内噪声（或控制混响时间）所需增加的吸声量来计算确定。当设计采用板状空间吸声体时，若吸声体的总面积相当于建筑物顶面积的30～40％，可使板状空间吸声体吸声的效率达到最佳值。而实际工程中为了满足降低噪声或控制混响时间的要求，空间吸声体的总面积宜取建筑物顶面积的40～50％。
