摘要
在分析隔板的低频隔声特性的基础上,本文通过两实例的分析比较,指出低频隔声遵从劲度定律,以及提高隔板劲度的有效方法.同时,还对影响隔声室低频隔声量的其它因素作了一些讨论.
On the basis of analysis of the plate performance at low frequencies, this paper proves that low frequency sound transmission loss differs to stiffness law, and proposes the effective way of improving the plate stiffness through twb examples. Meanwhile, other factors which affect the perfor-mance of sound insulation room at low frequencies are discussed in detail,
