Abstract：Three types of air-solid sonic crystals noise barriers were established for the tyre-road noise which is the main noise of highway by using recycled columns of the fence. Comsol Multiphysics was used to calculate the corresponding band structure and explore the influencing factors of band gaps. The results showed that the three forms can generate corresponding band gaps; the wall thickness had little effect on the band gap width, but the hollow scatterers could generate a complete band gap at low frequencies; opening treatment of the scatterers could effectively increase the low band gap width; after the lattice filling rate reached 0.5, complete band gaps were generated in order from high to low frequencies, and as the filling rate increased, the band gap overall width increased. The noise reduction characteristics of the barrier were verified through a combination of simulation and indoor experiments, the sonic crystals noise barrier had good noise reduction performance in the band gap range, compared with the aluminum alloy composite board noise barrier with the same specifications. The low-frequency noise reduction effect was increased by 1~16dB, and the high-frequency noise reduction effect was increased by 1~2dB; however, after 1600Hz, the noise reduction effect of the sonic crystals noise barrier did not outperform the composite board barrier, and the noise reduction effect was greatly affected by the number of cycles. The sonic crystal noise barrier is a promising combination of new noise reduction concepts and green environmental protection.
