The residential sound barrier is to reduce the noise of people's living places. Most of the places where people live are close to highways, and people's residential quarters need a quiet living environment. Still, noise problems such as traffic flow have always been a drawback of reducing residential areas' environmental quality, so the community's sound barriers have arisen at the historic moment.
Residential sound barrier/noise screen composition :
The residential sound barrier is mainly composed of structural steel pillars and sound insulation screen panels. The pillar is the main force-bearing component of the sound barrier. It is fixed to the road crash wall or the embedded steel plate next to the track by bolts or welding; The soundboard is the main sound-absorbing and sound-absorbing member, and it is fixed in the H-shaped column groove by a high-strength spring clip to form a community sound barrier. (The color, material and molding thickness of the residential sound barrier can be customized according to actual needs.)
Residential Sound Barrier / Sound Screen Size:
Material: aluminum sheet, galvanized sheet, transparent acrylic sheet, 5 5 tempered glass (laminated glass), FRP
Hole type: Louver hole type micro-perforated type
Sheet thickness: 0.8-1.0mm (can be customized as required)

A variety of colors and shapes can be selected for combination, and the landscape effect is ideal. It can be designed according to user requirements in various styles and the environment in harmony with the surrounding environment to form a beautiful landscape.
Upright residential sound barrier, the overall shape is straight, and the upper sound absorption plate is solitary, which can more effectively control the diffraction of sound through the upper part of the screen, with a continuous frame structure as the main body in the middle
Arc-shaped residential sound barrier, especially good noise reduction effect; both beautiful and good noise reduction effect;
Sound barriers for air conditioning units
The sound barrier is based on the upright sound barrier. The upper part of the sound barrier is folded in the direction of the road, and the angle is less than 45 degrees. The side facing the road is usually made of sound-absorbing surface. The support of the sound barrier is mostly made of h-shaped steel. This sound barrier can increase the sound path difference and improve the noise reduction effect, but the materials have specific requirements and high construction technology. To reduce the wind load and make the sound barrier safe, the sound barrier of the air-conditioning unit generally selects a sound barrier larger than 5m to use a corner-type sound barrier.
Cooling tower sound barrier
The design of the cooling tower's sound barrier should consider the working principle of the cooling tower: The cooling tower uses the cold and heat exchange after water and airflow to generate steam. An evaporative cooling device that dissipates waste heat generated in industry or refrigeration and air conditioning reduces the water temperature to ensure the regular operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.
Comparison of noise reduction before and after the sound barrier of the cooling tower is installed: The sound level at the bottom of the cooling tower: 95dB 30 meters away from the bottom of the residential building: 65dB Design value of the bottom of the Cooling tower sound barrier:
The main components of a cooling tower's sound barrier are the foundation, columns, screens, fixtures, seals, and some include the top structure.
1) Sound barrier screen body: galvanized sheet, backplate, keel, glass wool, DuPont film, front punching rate above 25%;
2) Sound barrier column: H-shaped steel, flange chassis, diagonal brace, inner rib plate, External ribs; adjustment of acoustic design:
3) According to calculations, the height of the sound barrier of the cooling tower is below 7m, and the engineering cost is still affordable;
4) In addition, the height of the sound barrier of the cooling tower is considered in consideration of the influence of wind pressure, and the strength of the crash wall Should not be higher than 5m;
5) General noise reduction of 3dB, residents feel that noise has decreased;
Overall arc sound barrier
Arc sound barrier there are a lot of different classification, which is an overall arc sound barrier inside these categories, then combine this situation now, when designed primarily for such products is to Different uses, because in many occasions, it is necessary to use a completely closed type, and if the closed type does not use an arc, it is really a waste of material, and it will have a specific effect on the reflection and isolation of the sound. Influence, so now use this overall arc design, then cater to the highway, factory, and office area needs. The key is that this product design can achieve good aesthetics, many people are very obvious after seeing like.
There are many different classifications of large curved sound barriers, of which the overall curved sound barrier is one of these classifications. When looking at the current situation, such products are mainly designed for different uses.
Because in many occasions, it is necessary to use a completely closed type, and if the closed type is not used, it is really a waste of material, and it will have a certain impact on the reflection and isolation of the sound, so now The use of this overall curved design meets the needs of today's highways, factories and office areas. The key is that this product design can achieve good aesthetics. Many people obviously like it very much after seeing it.
From the classification of the railway sound barrier itself, because the materials used are different, there are many differences in the specific classification. Among them, the PC board is the most used, and of course, the perforated board is also used. There are also some in the classification. Using aluminum-zinc type materials, and comprehensively, the PC board is the best one now. When combined with this situation, the overall arc shape can be better used, and it can be used very well. It's a better way to satisfy people with good characteristics.
When considering the sound barrier of the cooling tower itself, the characteristics are very obvious, because it can achieve good impact strength, and the strength coefficient can reach 250 times higher than the glass, because In the design, it is necessary to have this type of strength. If this strength is not achieved, of course, many adverse effects will occur. It is true that this approach is very serious and needs to be rationalized. Look is also known as a "transparent steel plate", so the effect is definitely very different.
Of course, when the tensile effect of the noise barrier is affected, it is now used at a temperature of 120 degrees Celsius to directly reach a tensile strength of 350 kgf per cubic centimeter, so the impact is still great And the bending strength is also very good. The reason why it can achieve the arc shape is because the bending strength itself is very large, basically no problem will occur at 90 degrees Celsius.
The sound barrier is mainly composed of a steel structure pillar and a sound-absorbing sound insulation panel. The pillar is the main force-bearing component of the sound barrier. It is fixed on the road crash wall or the embedded steel plate next to the track by bolts or welding; sound insulation The board is the main sound-absorbing and sound-absorbing member, and it is fixed in the H-shaped column groove by a high-strength spring clip to form a sound barrier. The design of the sound barrier has fully considered the problems of elevated highways, urban light rails, wind loads of subways, collision safety of traffic vehicles, and weather protection in the open air. It has a beautiful appearance, exquisite manufacture, convenient transportation and installation, low cost and long service life. It is especially suitable for noise prevention of elevated highways, urban light rails and subways.
Highway sound barrier is a facility that is inserted between the sound source and the receiver in order to block the direct sound between the sound source and the receiver. It causes a significant additional attenuation of sound wave propagation, thereby reducing the effect of noise in a certain area where the receiver is located.
With the improvement of living standards, the rapid increase in the number of urban motor vehicles, and the rapid development of transportation arteries, traffic noise has increasingly become the main noise in cities. Traffic noise mainly refers to the noise generated by motor vehicles running on the city's main transportation lines. Noise generated by other transportation vehicles, such as airplanes, trains, and automobiles (such as airplanes, trains, ships, etc.) during flight and travel. We all know that traffic noise has a great impact on people's health, so we should minimize traffic noise and the usual protective measures.
The bridge sound barrier inserts a facility between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called a bridge sound barrier. During the propagation of sound waves, when encountering the bridge's sound barrier, three phenomena: reflection, transmission, and diffraction occur. A bridge sound barrier is inserted between the sound source and the receiving point. The bridge sound barrier is infinitely long. Sound waves can only diffract from above the bridge sound barrier, and then form a sound shadow area, as if light is blocked by an object. Like a shadow. In this sound and shadow area, people can feel that the noise is significantly reduced. This is the noise reduction effect of the bridge sound barrier.
