A study of noise reduction by high-rise balcony

Abstract

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.

高層住宅中的陽臺不僅具有居住及建筑上的功能，對道路交通噪聲也有衰減作用。本交通過建立噪聲傳播模型計算高層住宅陽臺的插入損失，并探討了影響陽臺降噪量的一些因素。同時對陽臺內部吸聲處理的效果進行了理論預測。
