Noise barriers are solid construction between noise resources and sound-sensitive receivers. They can't reflect or absorb all noises but only reduce overall noise levels. Common effective noise barriers include reflective and absorptive sound barriers. Typically, they can reduce noise levels by 5 to 10 decibels (dB). Roads, highways, retail and big-box stores, construction sites, overpasses and bridges which locate near populated areas are generally equipped with these sound barrier systems.
Hebei Huanyu Noise Barriers Co., Ltd. is a professional manufacturer of soundproofing products. Our outdoor sound barrier mainly includes gabion baskets, aluminum, PVC sound barrier and transparent sound barrier like polycarbonate and acrylic. Generally speaking, a sound barrier system is a combination of two materials such as polycarbonate and aluminum which supports the clear barrier.
Excessive noise pollution has been a hazard and caused serious affects to people’s health and daily life, especially for children and old people. You see, old people who often have heart problem, may have life risk when a sudden noise occurs. In addition, noises can greatly affect people’s moods and reduce work efficiency.
A noise barrier system can be roughly divided into reflective and absorptive. Reflective barriers such as stone, metal and PVC have hard and smooth surface and thus block sound toward the resources or beyond. When the sound wave hit hard surface, some energy is transmitted through the wall but the bulk is reflected back.
Absorptive noise barrier are usually designed with perforated holes or slits on surface. They make easy transportation of the sound into the interior of the wall. In the interior part, it is filled with soundproofing materials such as fiber glass and wool glass which can eliminate noises.
With the development of economy, the number of vehicles and industries are rapidly increased. They have greatly improved people's living level. Simultaneously, terrible noises pollute silent residential or commercial areas and affect normal dweller’s living. As to sound barrier, there are a lot of options. Except concrete soundproofing wall, aluminum, polycarbonate, PVC and gabion wall are also extensively found in heavy traffic or industrial areas.
Industrial plants and big-box stores are two familiar noise resources. They should be equipped with sound barriers to lower noise level.
Traffic noise barriers are designed to minimize noise damage to residential, commercial or dwellers near highway, roads and big-box stores.
My house is close to the high way station, so it's hard for my families to fall asleep accompanied by the noise of the trains. Half year ago, I bought your polycarbonate sound barrier and installed it surrounding my house. Thanks for the barrier, it's better than before, we can have a good sleep.
Several months ago, I bought many acrylic noise barrier panels for our office building, and we installed them easily. I think acrylic noise barrier is a great option as office sound barrier to avoid the talking or joking disturbing. And this kind of barrier gives people a clean and fashion feeling. I love it!
I bought some PVC sound barrier sheets and installed them in my factory. The barrier's weight is lighter than aluminum sound barrier. It's easy to transport, I like it. And the color of PVC sound barrier is bright; smooth surface can greatly reflect the noise.
I have bought gabion sound wall for several years, it's still as new as before without rust. And it's installed at the roadside. It not only resists the noise of cars, but also decorates the road, and gives passengers a beautiful view.
