Road Noise Barrier is a sound insulation facility. In order to shield the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the influence of noise in a certain area where the receiver is located. Here is a brief introduction to the four common types of Road Noise Barrier. The four common types of Road Noise Barrier are: resistive Road Noise Barrier, ordinary transparent Road Noise Barrier, microplate transparent Road Noise Barrier and composite Road Noise Barrier.
Ordinary transparent Road Noise Barrier: Ordinary transparent Road Noise Barrier uses transparent polycarbonate board (also known as PC board), because it is transparent, Road Noise Barrier has a better sense of landscape and is easier to dissolve into the surrounding environment.
Composite Road Noise Barrier: Composite Road Noise Barrier has the advantages of both transparent and opaque Road Noise Barrier. One half of it is a resistive Road Noise Barrier, and the other half is a transparent Road Noise Barrier. The height of the above four Road Noise Barriers can be combined freely according to the design requirements, and the road screen can also be customized according to customer requirements.
Microporous plate transparent Road Noise Barrier: Microporous plate transparent Road Noise Barrier has 2 layers. It applies the principle of microporous sound absorption. Many small holes with a diameter of 0.8mm are pierced on a polycarbonate plate with a perforation rate of 1%. The other layer of polycarbonate board is not perforated, and the distance between the two layers is 100mm. It is equivalent to a single-layer microporous sound-absorbing structure, which solves the contradiction between sound absorption and transparency. Due to the effect of sound waves, the micropores will not be blocked by dust.
Resistive Road Noise Barrier: The Resistive Road Noise Barrier consists of a front panel, a rear panel, and a side panel to form a closed box structure, forming a modular unit. The front plate is a galvanized steel sheet with a perforation rate of 25%, and the back and side plates are galvanized steel sheets with no perforation. A moisture-proof centrifugal glass wool board is filled between the two layers, and the sound-absorbing material is covered with a polyfluoroethylene film. The uprights are 12# I-steel, and the column spacing is 2m. The uprights are inserted into the reinforced concrete foundation. The standard board is inserted between the I-beams and fixed with fasteners. Installation, maintenance and replacement are extremely simple.
