摘要
通过对 8处林带降噪效果的测试 ,得出了林带总的衰减、愈量衰减与宽度、能见度的定量关系 ,并对衰减进行了频谱分析 。
Through investigating the noise attenuation of 8 tree belts,the relationship between the total noise attenuation,excess attenuation and width,visibility are found,the frequencies of the noise attenuation analyzed and practical suggestions concerning design of tree belts of highway for noise reduction provided in this paper.
