| Abstract: | A novel composite type of sound barrier has been developed by using the re-cycled tyre and cement board stressed and perforated,and through experiments and theory it is validated that its absorbing sound performance is good and its sound absorption coefficient comes up to 0.62.So the kind of sound barrier can be used to reduce the road noise.Last,the installation of the sound barrier is introduced. |
