We can see a erected barrier on both sides of highways and train tracks. What is this for? What is this? In fact, it is a sound barrier specially set up to isolate noise. Trains, cars, etc. will generate a lot of noise during driving, which will cause some problems to the surrounding residents. To solve this problem, a sound barrier has appeared, which can effectively isolate noise. In principle, it isolates the propagation of sound waves, and gradually attenuates the sound waves to a certain extent. This is the biggest effect of the sound barrier-the noise reduction effect. Since there are many sound barrier manufacturers , I will take you to familiarize yourself with a few good sound barrier manufacturers for consumers' reference when buying!
Main classification of sound barrier
The sound barrier can be divided into the following categories according to the material: metal sound barrier (metal louver, metal screen mesh), concrete sound barrier (lightweight concrete, high-strength concrete), PC sound barrier, FRP sound barrier, etc. The tempered plexiglass sheet with a maximum width of 2.7 meters wide has been officially produced in Wuxi. The sound barrier factory was successfully installed, which greatly improved the visual and noise reduction effects.
According to different uses, it can be divided into these categories: railway sound barriers {[1], highway sound barriers [2], urban landscape sound barriers, noise reduction barriers in residential areas, etc.
Application range of sound barrier
Sound barriers are mainly used along railways and highways,
Sound barriers are mainly used for sound insulation and noise reduction in traffic and municipal facilities such as highways, elevated composite roads, urban light rail subways, etc., to control the impact of traffic noise on nearby urban areas, and can also be used for sound insulation and noise reduction in factories and other noise sources.
Sound barriers are divided into reflection-type sound barriers with pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is made with more effective sound insulation. Most sound barriers use a combination of sound absorption and sound insulation products, which are characterized by targeted control of the generation and transmission characteristics of road noise. For example, the friction sound of cars and roads or the friction sound of locomotives and rails is on the lower part of the road, and the sound has the characteristic of diffracting through the upper part of the screen body. In the middle of the sound barrier, a transparent reflective sound insulation board is used, which can effectively interrupt the propagation of sound waves; at the same time, it also provides a wide field of vision environment for drivers and residents. In the field of architectural acoustics, through acoustic management, reverberation time and indoor acoustic environment are controlled to meet the requirements of professional venues.
Selection Principle of Sound Barrier
The general principles for the selection of sound barrier materials are good noise reduction performance, safe and reliable structure, economical material prices, low installation costs, durability, long service life, landscape coordination, and beautiful appearance. The specific instructions are as follows:
(1) Large sound insulation: the average sound insulation should not be less than 35dB;
(2) High sound absorption coefficient: the average sound absorption coefficient should not be less than 0.84;
(3) Weather resistance and durability: The product should have water resistance, heat resistance, UV resistance, and will not reduce performance or quality abnormalities due to changes in rainwater temperature. The product adopts aluminum alloy coiled plate, galvanized coiled plate, glass wool, H steel column surface galvanized surface anti-corrosion years of more than 15 years.
(4) Beautiful appearance: a variety of colors and shapes can be selected to combine with the surrounding environment to form a beautiful landscape.
(5) Economic: Prefabricated construction, improve work efficiency, shorten construction time, can save construction costs and labor costs.
(6) Convenience: Installed in parallel with other products, easy to maintain, and easy to update.
(7) Lightweight: The sound-absorbing board products have the characteristics of light weight, which can reduce the load bearing of elevated light rails and elevated roads, and can reduce the cost of the structure.
(8) Fire prevention: Ultra-fine glass wool is used. Due to its high melting point and non-flammability, it fully meets the requirements of environmental protection and fire prevention regulations.
(9) High strength: Combined with different climatic conditions in various regions of China, the full wind load should be fully tested during structural design. The grooves are pressed through the production line to increase strength.
(10) Waterproof and dustproof: The material design fully considers waterproof and dustproof, and its sound absorption performance is not affected in the dust or rain environment. Dust discharge and drainage measures have been set in the structure to avoid water accumulation inside the components. The sound absorption performance of the micro-perforated resonant cavity is not affected in the rain environment, and the noise reduction is particularly obvious for low and middle frequencies.
(11) Durability: The product design has fully considered the road's wind load, the impact safety of traffic vehicles, and the full-air fake outdoor corrosion protection. The product adopts aluminum alloy coil plate, galvanized coil plate, glass wool, H steel column surface galvanized treatment. During the warranty period, it will not corrode, change shape, sound absorption and sound insulation effect.
Sound barrier manufacturers
Sound barrier manufacturer: Shanghai Zhongchi Group Co., Ltd.
Since 2005, Zhongchi Group has embarked on the road of independent research and development and production of sound barriers, and has continuously introduced high and new technologies to make the production of sound barriers of higher quality. Zhongchi Group has always focused its research and development goals on the noise reduction of sound barriers, and strives to create a noise-free environment. At the same time, Zhongchi Group also pays attention to the research and development of the most beautiful sound barrier, so that the sound barrier has local customs and can become a part of the beautifying environment. Both of these goals are the direction of Zhongchi Group's struggle. After ten years, the sound barrier produced by Zhongchi Group has been applied in many engineering buildings.
Sound barrier manufacturer: Foshan Hengchu Transportation Environmental Facilities Co., Ltd.
Sound barriers, protective nets, noise barriers, etc. are the objects of research and production by Hengchu Transportation Environmental Facilities Co., Ltd. After years of research and development, it has successfully occupied an important position in southern China, and its products can be seen in many roads, railways, and factories. Among them, important national projects such as Beijing-Shanghai Railway and Wuhan-Guangzhou High-speed Railway use products produced by Hengqiu. The sound barriers of Hengchu have been tested by the Ministry of Communications and also by the relevant departments of Shanghai Fudan University, and they can definitely be trusted in terms of quality.
Sound barrier manufacturer: Hebei Taihengtong Environmental Protection Technology Co., Ltd.
Taihengtong Environmental Technology Co., Ltd. is a manufacturer specializing in making sound barriers. Over the years, they have participated in many major projects. For example, Tangshan Road Bridge West Outer Ring Sound Barrier Project, Beijing Badaling Shahe Interchange Bridge Sound Barrier Project, Inner Mongolia Tongliao High Speed ​​Sound Screen Project, Zhang Cheng High Speed ​​Sound Screen Project, etc. For so many years, Taiheng's products can be recognized by everyone. There is also a reason for serious work attitude, cost-effective products, and quality after-sales service, which are the reasons for attracting customers to choose Taiheng.
Editor's summary: The existence of a sound barrier is very necessary and important. It is precisely because of the existence of the sound barrier that the residents around railways and highways can be assured to live in peace. For remote places, places subject to sandstorms and windstorms, the sound barrier is also a good line of defense to protect the surrounding environment.
