摘要

在公路沿线安装隔音墙，以减少邻近社区的公路交通噪音。基于安装或老化的影响，一些隔音墙在面板之间有小的间隙。由于现场条件的限制，使用传统的屏障插入损耗测量来比较有间隙和没有间隙的截面可能是不可能的。在本研究中，在间隙位置和可比较的参考(非间隙)位置收集屏障邻近的声级，以确定紧接在屏障后面的间隙效应。然后采用两种方法来确定这些差距效应如何转化到附近的社区。宽带和频谱声级都进行了分析，以确定一个小间隙(高达0.5英寸高，10英寸长)的影响在屏障附近可以达到2分贝，但随着距离的增加而迅速减少。

Using barrier-adjacent measurements and predictions to determine effects of small gaps in highway noise wall

Noise walls are installed along highways to reduce highway traffic noise in adjacent communities. Based on installation or aging effects, some noise walls contain small gaps between panels. Applying traditional barrier insertion loss measurements comparing sections with and without gaps may not be possible due to site conditions. For this study, barrier-adjacent sound levels were collected at gap locations and comparable reference (non-gap) locations to determine the gap effect immediately behind the barrier. Two methods are then applied to determine how these gap effects translate to nearby communities. Both broadband and spectral sound levels are analyzed to determine that the effects of a small gap (up to 0.5 inches in height and 10 inches in length) can be up to 2 dB near the barrier but diminish rapidly with distance.

期刊介绍： Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
