高层住宅阳台降噪量的计算分析

A study of noise reduction by high-rise balcony

高层住宅中的阳台不仅具有居住及建筑上的功能，对道路交通噪声也有衰减作用。本交通过建立噪声传播模型计算高层住宅阳台的插入损失，并探讨了影响阳台降噪量的一些因素。同时对阳台内部吸声处理的效果进行了理论预测。

In a city with high density of traffic flows, balcony can be incorporated in the architectural design of high rise residential buildings, not only as a vital space for the inhabitants, but also as an effective noise abatement element. This paper investigates the mitigation of road traffic noise by balcony in high-rise residential building and predicts the insertion loss of a balcony. Finally, an acoustical treatment is proposed to reduce the impact of road traffic noise.
