Sound Barrier Panel are acoustic baffles specifically designed to mitigate the effects of highway traffic noise on the surrounding environment. They are usually installed on both sides of the roadway as wall constructions that reduce noise levels by absorbing and insulating sound waves. These absorptive panels can be categorized into reflective barriers that are purely sound-insulating and composite barriers that combine sound absorption and sound insulation, with the latter providing more effective noise reduction.
The classification of highway sound-absorbing panels can be divided into roadside noise barriers, tunnel noise barriers and sound barriers according to the application scenarios. Roadside noise barrier is usually set on both sides of the highway, used to absorb roadside noise; tunnel noise barrier is usually set in highway tunnels, used to absorb tunnel noise; sound barriers are usually set between the highway and the residential area, used to absorb highway noise, reduce the impact on the residents.
These acoustic panels are designed with a variety of factors in mind, including weather resistance, durability, acoustic performance, fire resistance, structural strength, water and dust resistance, lightweight, aesthetics, and economy to ensure that they can be used effectively in a variety of environments.
The process of producing these acoustic panels has the following characteristics:
- Material selection: sound-absorbing panels are usually produced using materials such as aluminum alloy coils, galvanized coils, glass wool, etc. These materials have good weather resistance and durability.
- Acoustic performance: The acoustic panels are designed with a high absorption coefficient in mind, and the average absorption coefficient should be no less than 0.84 to ensure effective noise reduction.
- Structural design: The wind load under different climatic conditions is fully considered in the structural design, and the strength is increased by pressing the grooves through the production line.
- Waterproof and dust-proof: waterproof and dust-proof are fully considered in the design, so that the sound-absorbing performance will not be affected in dusty or rainy environments.
- Lightweight: the sound-absorbing board series products are characterized by light weight, which can reduce the load of elevated light rail and elevated road and lower the cost of structure.
