玻璃棉板 Glass Fibre Plate
玻璃棉制品是理想的吸声材料,和其他绝缘材料相比,玻璃棉制品的吸声效果是好的,下面吸声系数是采用混响室法,吸声系数是在频率为250、500、1000、2000Hz时测定的平均值。
Glass wool products is an ideal sound-absorbing materials,and compared to other thermal insulation materials,sound-absorbing effect of glass wool products are the best,following the sound absorption coefficient by reverberation room method is,sound absorption coefficient is at frequencies of 250,500,1000,when the measured aveage.
