Noise screens: design and features

A noise barrier is a structure that is usually erected on major roads with heavy traffic to reduce the noise generated by traffic. Screens are used to protect not only highways, but also railway lines passing through the settlement, and to reduce noise from industrial facilities located near a residential area.

On the site mpmetall.site you can order the right amount of building materials that differ in quality, practicality and endurance. The cost of this material when buying in bulk can be relatively low, which must be taken into account when filling out an application for the purchase of material as expected and in the right quantity.

The lower part of the faucet is a strong opaque material, mainly a fiberglass construction of a plaster-coated composite screen. This part has the greatest strength, wear resistance, since it is the main part of the flying stones from under the transportation wheels. Further, pillars with a similar base of material for fastening are attached to the base. They protect the soundproofing panels, so they need to be of stronger construction and materials.

A panel consisting of shockproof material is inserted into the resulting frame from the base and pillars, this is usually plexiglass or other material. The material from which the panel is made differs, depending on what type of screen is being constructed.

Polymer and plexiglass are usually used for transparent structures. For an opaque screen, metal leaves with perforated surfaces are used, sound-absorbing back surfaces.

In fact, the manufacture of noise barriers is acceptable on the basis of a variety of materials. The height of the fence is 8 m, but not more. The use of transparent material is associated with the need to ensure visibility on the track, as well as ensure safety on the track.

To protect against noise, soundproof screens are used, which protect not only the surrounding structures of the freeway, but also the highway itself. The essence of the actions of these structures is to take on all the waves of noise. Such screens have perforated holes designed to remove noise. Such designs have a metal frame and polycarbonate screen plates.
