摘　　要：本文就当前存在的临街高层住宅降噪问题展开研究,提出了一种新型建筑构造——通风隔声窗。本文主要讨论了新型通风隔声窗对于点声源噪声的降噪可行性,首先对点声源在小型声屏障下的传播进行了理论推导,而后分析了在点声源交通噪声前提下小型声屏障在顶部通风凸窗中的可行性,并得出了这种新型通风隔声窗具有很强实用价值的结论。In this paper,aiming at the existed problem of noise reduction for street high-rise residential buildings, a new building envelope named ventilation sound proof window was presented. Firstly, the noise reduction feasibility for point source noise of this new kind of window was discussed. And then, the communication theory of point sound source with small acoustic barrier was deduced. Furthermore, under the point sound source of traffic noise condition, the feasibility of small acoustic barrier installed at the top of the window was analyzed. It was concluded that this new sound proof window was of great practical use.
