A facility is inserted between the sound source and the receiver to make the sound wave propagate with a significant additional attenuation, thereby reducing the effect of noise in a certain area where the receiver is located. Such a facility is called a Noise Barrier. The general principles of Road Noise Barrier material selection are good noise reduction performance, safe structure, economical material price, low installation cost, durability, long service life, coordinated landscape, and beautiful appearance.
Selection criteria for Road Noise Barrier:
- Large sound insulation: the average sound insulation should not be less than 35dB; high sound absorption coefficient: the average sound absorption coefficient should not be less than 0.84;
- Weather resistance and durability: Road Noise Barrier should have water resistance, heat resistance, UV resistance, and will not reduce performance or abnormal quality due to changes in rain temperature. The products adopt aluminum alloy coils, galvanized coils, glass wool, and H-steel columns with galvanized surface and anti-corrosion period of more than 15 years.
- Beautiful: You can choose a variety of colors and shapes to combine to coordinate with the surrounding environment to form a beautiful landscape.
- Economical: Road Noise Barrier assembly-type construction improves work efficiency, shortens construction time, and saves construction and labor costs.
- Convenience: Parallel installation with other products, easy maintenance and easy updating.
- Lightweight: Road Noise Barrier has the characteristics of light weight, which can reduce the load-bearing load of elevated light rails and elevated roads, and can reduce structural costs.
- Fire protection: Ultra-fine glass wool is used, which is non-flammable due to its high melting point, which fully meets the requirements of environmental protection and fire protection regulations.
- High strength: In combination with different climate conditions in various regions, the Road Noise Barrier fully considers the virtual wind load in the structural design. The groove is pressed through the production line to increase the strength.
- Waterproof and dustproof: Road Noise Barrier Waterproof and dustproof are fully considered in the material design. The sound absorption performance will not be affected in the environment of dust or rain. Dust drainage and drainage measures have been set in the structure to avoid water accumulation in the components. The sound absorption performance of the micro-perforated resonance cavity is not affected in a rainy environment, and the noise reduction is particularly obvious for the middle and low frequency.
- Durable: The design of Road Noise Barrier has fully considered the wind load of the road, the collision safety of traffic vehicles and the outdoor anti-corrosion of full air. The product adopts aluminum alloy coil, galvanized coil, glass wool, and H steel post with galvanized surface treatment. During the warranty period, there is no corrosion, no change in shape, sound absorption and sound insulation effect.
