Sound absorbing materials. Sound absorption measurement method in reverberation room

HB 7126-1994 航空材料和构件的混响室法吸声系数测量

本标准规定了在混响室中测量航空材料、机舱壁板或装饰板的吸声系数，以及测量座椅、人、空间吸声体的吸声量的方法。 　　本标准适用于在混响室中对材料、构件、空间吸声体的吸声系数声量测量，但不适用于测量弱阻尼共振器的吸声特性

GB/T 20247-2006 声学.混响室吸声测量

本标准规定了在混响室内测量用于处理墙壁或顶部等界面的声学材料的吸声系数、或诸如家具、人、空间吸声体等的吸声量的方法。该方法不适用于测量低阻尼共鸣器的吸声特性。 测量结果可用于有关室内声学和噪声控制的数据比较及设计计算
