Road barrier tunnel

Railway sound barriers have also become railway sound insulation walls and high-speed railway sound barriers. It is a sound barrier designed based on the noise generated by the current high-speed railway trains operating at a speed below 200KM/H. The design of such products has fully considered the wind load of elevated highways, urban light rails, and subways, the impact safety of traffic vehicles, and all-weather open-air anti-corrosion issues.

The height of the railway sound barrier is between 1M and 5M, and the average coverage effective area is 10~15DB(A) (125HZ~40000HZ, 1/3 octave), and the maximum is 20DB(A). Generally speaking, the higher the sound barrier, or the further away from the sound barrier, the better the sound reduction effect.
