Key Features of Road Sound Barrier:
Sound Insulation: Average sound insulation of 35dB.
2. High Sound Absorption Coefficient: Average absorption coefficient of 0.84.
3. Weather and Durability: The product boasts water resistance, heat resistance, UV resistance, and will not degrade in performance or quality due to changes in temperature from rain.
The noise reduction amount of road noise barriers depends on factors such as the frequency of the noise, the height of the barrier, and the distance between the noise source and the receiving point. The noise reduction effect of road noise barriers is significantly related to the frequency components of the noise. It is more effective in reducing noise at frequencies above 2000Hz compared to mid-frequency sounds around 800-1000Hz. However, for low-frequency sounds around 25Hz, the effect is poor due to the longer wavelength of sound waves, which can easily diffract around the barrier. Generally, metal noise barriers can reduce noise by 10-15dB for high-frequency sounds. The height of metal noise barriers can be designed based on the distance between the noise source and the receiving point. Doubling the height of the barrier increases the noise reduction by 6dB. To enhance the noise reduction effect of road noise barriers, it is advisable to position the metal barriers closer to the noise source or the receiving point.
Metal sheet thickness: 0.5—1.2mm (customizable to customer's requirements); molding thickness: 50mm—250mm etc. (customizable to customer's requirements). Road sound barrier uses aluminum alloy plates, galvanized steel plates, aluminum plates, H-shaped steel columns with zinc-plated and painted surface treatment for corrosion resistance, with a lifespan of 15 years or more.
Material of metal sound barriers: galvanized sheet, aluminum plate, color steel plate, iron plate, etc. Colors can be customized according to your drawings. High-quality craftsmanship, ample stock, factory direct sales of cooling tower sound barriers, residential area sound barriers, highway sound barriers, bridge sound barriers, and factory sound barriers.
