一种新型自然通风隔声窗的构造设计与分析

A new structure design and analysis of natural ventilation sound-proof window

为了进一步应对城市交通噪声的严重影响,提出一种新型的自然通风隔声窗构造,在双层窗隔声原理的基础上,利用单通道消声器原理,将多层透明微穿孔共振吸声结构设置在双层窗空腔内形成消声通道,指出该自然通风隔声窗在满足通风的前提下具有良好的隔声性能。

With adapting the urban traffic noise impact on the living environment, this paper proposed a new structure design of natural ventilation acoustic proof window. Based on double glazing windows principle, the transparent multilayer micro punch resonance sound absorption structure are arranged to form a double window noise channel in the cavity, by using the principle of single channel muffler. Point out the new natural ven-tilation sound-proof window has not only good noise insulation ability, but also a capacity of ventilation.
