摘要
道路声屏障结构形式研究一直是国外学者研究的热点课题,而国内从事声屏障理论研究的学者还不多。本文介绍国外研究的不同结构形式新型声屏障的降噪基本原理、性能特征及发展动态,并对它们的降噪性能进行了分析比较。
The research of configurations of road noise barriers is a hot topic that many foreign scholars have been studying.However,the minority of our national scholars have engaged in the theory study of noise barriers. In the paper, the basic principle to reduce noises, performance characteristics and developing trend of different novel noise-barriers are generally introduced. In addition, these noise barriers inducing-noise performances are compared.
