【摘要】 邦达不燃轻质板是一种新型建筑材料。介绍了该板与75mm轻钢龙骨组成的6种构造板墙实测的隔声特性。比较分析了板的不同层数和有无玻璃棉夹芯对板墙隔声的影响。从二层增加到四层,隔声量提高6dB;板墙中增加玻璃棉夹芯层,隔声量也提高6dB。带玻璃棉夹芯的四层板墙的隔声量高达60dB。更多还原

【Abstract】 BOMDER unburnting lightweight panel is a type of new building material . This paper introduced the measured sound insulation of the wall made of the panels and 75mm lightstell keels in six kinds of construction. We compared and analyzed the influences on the sound Insulation of the wall under the circumstances of with glass wool between the panels or without it and by changing the layer amounts of the panels on the two side of the keels. From two layers to four layers, the sound Insulation increased 6 dB. If the glass wool is filled in the wall,the sound insulation will also increase 6 dB. The sound Insulation of the wall that is made of four layers of the panels and filled in glass wool is up to 60 dB.更多还原
