In recent years, people pay more and more attention to the impact of Road Noise Barrier on noise and noise on the surrounding environment. It is especially suitable for the noise prevention of elevated highways, urban light rails and subways. Road Noise Barrier is the most ideal sound insulation and noise reduction in modern cities. facility.
When a high-speed Road Noise Barrier sound wave encounters a sound barrier during its propagation, there will be three phenomena: reflection, transmission and diffraction. Generally, the barrier can prevent the transmission of direct sound and make the transmitted sound have sufficient attenuation, while the influence of the transmitted sound can be ignored.
The sound insulation effect of Road Noise Barrier can generally be expressed by the amount of noise reduction, which reflects the above-mentioned two sound barrier capabilities of the sound barrier. A sound barrier is inserted between the sound source and the receiving point. The barrier is set to be infinite. Sound waves can only be diffracted from above the barrier, and a sound shadow area is formed behind it, just as light is blocked by an object to form a shadow.
In this sound shadow area, you can feel that the noise is significantly reduced, which is the noise reduction effect of Road Noise Barrier. Properly handling the impact of noise on the surrounding environment has gradually become the consensus of the whole society. At the same time, it has become the main noise source that affects people's normal rest. The installation of sound barriers has become the most direct and effective way to solve noise.
Construction of the basic scene of Road Noise Barrier:
- Road Noise Barrier foundation The foundation of the construction site is an ordinary soil layer as the concrete foundation of the sound insulation wall.
- The foundation construction of Road Noise Barrier is a concrete foundation, on which bars can be planted directly;
- The foundation construction of Road Noise Barrier is a concrete foundation, made of channel steel or other steel structures, used for sound insulation walls;
