Sound barrier is an indispensable part of urban roads, which mainly has the effect of reducing noise, so as to control the damage of noise to people. In the selection of sound barrier raw materials, it is important to fully consider the endurance plate, then whether this raw material can be made into sound barrier?

According to the grasp of the characteristics of the endurance plate, the endurance plate is not only simple to make, but also has high-quality sound insulation effect, so it has become a more extensive raw material in the sound insulation material, as a sound barrier, of course, there is no problem. How much noise can a sound barrier made of endurance panels reduce?

According to the test, the noise reduction of the endurance plate is related to the frequency of noise, the height of the natural barrier and the interval between the sound source and the receiving point. The noise reduction effect of the sound barrier is closely related to the frequency component of the noise, so the noise reduction effect of high frequency sound beyond 2000Hz is better than that of high frequency sound around 800 to 1000Hz. But for low frequency sound around 25Hz, the effect is poor. Therefore, in the case of using an endurance plate to build a sound barrier, in order to better make the noise reduction effect of the natural barrier very good, the natural barrier should be as close to the sound source as possible or the application of the sound barrier.
