This paper reviewed the advances of noise barrier structure in China, and illustrated the development of multiple-edged, T-shaped and Y-shaped top structures used for noise barriers abroad. The development of some new top structures, such as soft surface, quadratic residue diffusers surface of noise barriers was also introduced.
