【Abstract】 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.更多还原
