Survey and research on highway greenwood belt to reduce traffic noise

摘要

Based on the summary of the research on greenwood belt to reduce noise at home and abroad and the analysis of the acoustics mechanism, the authors carried through the measurement of the noise attenuation effect of greenwood belts in Hujia expressway, highway of Jinshan petrochemical plant and Hangzhou arboretum. Then we bring forward the semi-experience formula of greenwood belt applied to highway and traffic engineering. After the contrast of the value of field test and formula calculation, the paper considers it can be used in greenwood design and construction of highway.
