Let's talk about the unique advantages of highway noise barriers.

　　In China, there is not yet a complete set of solutions for the prevention and control of factory noise pollution. At present, the most commonly used are galvanized steel plate louver curtain sound insulation boards. Generally, my products have significant advantages in performance. Why is this so?

　　The strength and reliability of the galvanized steel plate-filled highway noise barrier are considered from an overall perspective. The use of special steel structure columns and galvanized steel plate raw materials increases both the overall strength and reliability of the noise barrier, and reduces its own weight.

　　Galvanized steel plate-filled highway noise barriers have excellent sound absorption properties: Using sound-absorbing materials, the sound barrier is currently a superior and effective centrifugal glass wool board and sound-absorbing cotton board with good waterproof and anti-fouling properties on the outer packaging, which can effectively ensure long-lasting sound absorption. Therefore, the average sound absorption coefficient of the sound barrier effectively reduces the transmission of noise to the public.

　　Hot-dip galvanized louver curtain sound insulation board has a good safety factor: The two columns use spring clips to fix the galvanized steel plate louver curtain hole sound insulation material, which is highly reliable. The sound absorption and thickness of the galvanized steel plate filler: According to the needs, the sound barrier selects the ideal color, which is harmonious with the surrounding scenery, simple and clear, the overall structure is smooth, the frame is smooth, and it meets the requirements of beautiful urban public transportation.

　　Basic Knowledge of Highway Noise Barrier Engineering Construction Projects

　　Outdoor highway noise barriers generally use bricks or reinforced concrete, while indoor noise barriers use thick steel plates, wood panels, plastic plates, paper-faced gypsum boards, and composite materials. The noise barrier is mainly composed of two parts: a steel structure column and a sound insulation and absorption board. The column is an important load-bearing prefabricated component of the noise barrier. It is fixed to the pre-embedded steel plate on the roadside guardrail or track by nuts or welding; the sound insulation and absorption board is the main sound insulation and sound absorption prefabricated component, and it is fixed to the H-shaped column body through a high-strength spring clip to form a sound barrier.

　　The design of the highway noise barrier has taken into account the wind load of elevated highways, urban light rails, and subways, the impact of vehicles, and outdoor corrosion problems due to weather conditions. It has a unique appearance, exquisite workmanship, convenient transportation and installation, low construction cost, and long service life. It is especially suitable for noise reduction applications in elevated highways and urban light rail and subway stations, and is an ideal noise reduction equipment for smart cities.

　　The height of highway noise barriers ranges from 1m to 5m. Generally speaking, the larger the sound barrier or the farther away from the sound barrier, the better the noise reduction effect. In the transmission process of sound waves, when sound encounters a sound barrier, three problems occur: reflection, scattering, and diffraction. Generally, natural barriers can block the transmission of direct sound, so that scattered sound has sufficient attenuation, and the effect of scattered sound can be ignored.

　　Therefore, the sound insulation effect of highway noise barriers can generally be described by the noise reduction amount, which reflects the ability of the sound barrier to shield and transmit sound. Inserting a sound barrier between the sound source and the receiving point, assuming that the natural barrier is infinitely long, the sound waves need to diffract over the natural barrier, but this creates a sound shadow area, like the shadow created when a light source is blocked by an object. Within this sound shadow area, we can feel that the noise is significantly reduced, which is the noise reduction effect of the sound barrier.
