noise cancelling barrier， roadside noise barriers， Sound barrier The sound barrier uses a hybrid sound barrier with a sound absorption unit on the top and a sound insulation unit on the bottom. After reasonably determining the length and height of the sound barrier, the noise can be reduced by 10-25 db (a). The sound barrier has a good noise reduction effect, and the sound insulation capacity is 10-25db (a). The structure is very safe and can resist natural and man-made damage. It has the advantages of low investment, fast construction speed and obvious landscape effect. No matter which material is used, the sound insulation layer is formed in the fixed unit first, and then it is fixed to a support with a certain resistance.

noise cancelling barrier， roadside noise barriers， Sound barrierThe metal column has the characteristics of high cutting resistance, high compressive strength, strong corrosion resistance and convenient installation. It mainly supports the weight of the sound barrier material of the cooling tower, the impact of the air flow generated by the driving of the vehicle, the possible natural wind, the impact of an accident, etc. The sound barrier is mainly composed of foundation, cylinder and sieve plate. The foundation is the main bearing capacity structure of the sound barrier, which can be designed separately or in auxiliary road facilities such as collision walls and road shoulders. At the same time, the design, shape and quality of the panel material will directly affect the noise reduction effect, landscape effect, service life, corrosion resistance, safety and reliability of the entire noise barrier.
