摘要
通过对公路声屏障不同声学元件声学性能的比较研究，阐明了两种声学元件在治理交通噪声中的差别，指出吸声共振型声学元件将是未来公路声屏障的发展方向。
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.
