Sound Barrier Highway Noise Barriers Aluminum PC or Acrylic Galvanized Sheet Wall Panel Fenicing

Product Description

Sound barriers are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers that are pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to wall structures installed beside railways and highways to reduce the impact of traffic noise on nearby residents. Soundproof walls are also called sound barriers. A facility is inserted between the sound source and the receiver to cause a significant additional attenuation of the sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called a sound barrier.

Classification

The bridge sound barrier inserts a facility between the sound source and the receiver, so that the sound wave propagation has an additional attenuation, so as to weaken the noise effect in a certain area where the receiver is located, such a facility is called the bridge sound barrier. In the process of sound wave propagation, when it meets the bridge sound barrier, three phenomena will occur: reflection, transmission and diffraction. A bridge sound barrier is inserted between the sound source and the receiving point, and the sound wave can only be diffused over the bridge sound barrier, and form an acoustic shadow region behind it, just as the light is blocked by an object to form a shadow. In this sound shadow area, one can feel the noise is significantly reduced, which is noise reduction effect of bridge sound barrier.
The composition of highway sound barrier: composed of steel structure column and sound absorption board. The column is the main stress component of the sound barrier, which is stabilized on the thick steel plate of the road anti-collision guardrail or the embedded parts on the side of the track by anchor bolts or electric welding. The sound absorbing board is the main sound absorbing component, which is stabilized in the H-shaped vertical rod groove with the help of high strength compression spring buckle to form the highway sound barrier.
Transparent board sound barrier adopts transparent polycarbonate board (also known as PC board), because it is transparent, the sound insulation barrier has a good sense of landscape and is easier to dissolve into the surrounding environment. The color is optional. The transparent panel sound barrier is composed of a screen body, a column and a flange, wherein the column and the flange play a supporting role; The screen body is used to absorb sound. The screen body is composed of a panel, a backplane and sound absorbing cotton. The panel is an open surface, which can be opened into round holes, louver holes and micro holes. The back plate is flat, blocking sound transmission; The sound absorbing cotton is in the screen body, and the sound enters through the panel hole, so that the sound absorbing cotton absorbs and weakens the sound, and the backplane blocks the noise to reduce. The sound barrier has the characteristics of durability, practicality, wind resistance, fire resistance, corrosion resistance, novel shape, convenient transportation, high quality and low price

Centrifugal glass wool is the international rise in the 1980s of new thermal insulation materials. It has flame retardant, non-toxic, corrosion resistance, small volume weight, low thermal conductivity, strong chemical stability, low moisture absorption rate, good hydrophobicity and many other advantages, is recognized as the most superior performance of thermal insulation, heat insulation, sound absorption material, has a very wide range of uses.

 

The aluminum fiber sound absorbing board is a kind of metal type sound absorbing material which is made of two sides of aluminum plate mesh, and the aluminum fiber felt and aluminum foil are sandwiched between them. It has excellent sound absorption performance, high tensile strength, ultra-thin light weight, convenient transportation and storage, good weather resistance, good decoration, easy processing and construction installation, recyclable use and other characteristics.

 

Aluminum foam is made of pure aluminum or aluminum alloy after adding additives, through the foaming process, while both metal and bubble characteristics, is a new type of porous sound absorption material.
