摘要
基于墙体空气声隔声现场测量方法,对不同构造的轻型木结构内墙进行了隔声试验研究,研究内容为弹性横槽和隔音毡对墙体隔声性能的影响,以及其与墙骨柱规格的关系。结果表明,弹性横槽对墙体隔声性能提升显著,对墙骨柱尺寸较大的墙体效果更明显;隔音毡在高频段的隔声性能良好,对不同规格的墙体效果无明显差别。
In this paper, field measurement of airborne sound insulation was carried out on the interior walls of wood frame construction with different structures.Resilient channel and deadening feltwere mainly studied on sound insulation performance of the wall with different studs. The results showed that the increase in STC wassignificantfrom the installation ofresilient channel, especially of larger wall. Deadening felt showed great sound insulation performance in high sound frequencies of the walls without obvious difference.
