| Abstract: | The difference to treatment of a traffic noise by two kinds of
acoustic components is expounded through a comparative study of the acoustic properties of
different acoustic components for a highway sound barrier,which points out that the acoustic
component of sound absorption resonance will be the trend in the future.The conclusions from this
research are a more important reference for the design of highway sound barrier. |

| Keywords: | diffusion\|reflection type sound absorption resonance type and highway sound barrier |
