Road and highway traffic noise is one of the worst noise pollution problems worldwide. As urban and residential sprawl encounters heavier and heavier traffic loads on nearby roads and highways, residents and communities are demanding better noise abatement from their local officials and DOT’s. Sound Fighter® Systems’ Absorptive Noise Barriers have proven to be very effective and durable in assisting with highway noise barrier walls and road noise reduction for over 30 years.
Our Sound-Absorptive Barriers effectively provide road noise reduction for:
| Name | Noise barrier/acoustic pannle barrier/sound barrier |
| Length | ≥0.5m |
| Hight | Customed |
| Thickness (unit piece) | ≥50mm |
| Material | aluminum ,galvanized steel sheet , acrylic/PC,etc |
| Function | Used in road |
| Brace | 100*100*8mm and offer customed |
| Flange plate | customed |
| Packing | PE film and Whaterproof material |
| RW | ≥35dB |
| NRC | ≥0.84 |
| Post | H steel post |
| Post size | Depend on the size |
While reflective products like concrete have been the traditional material for outdoor noise barrier walls & enclosures, the advanced sound-absorptive materials found in Sound Fighter® Systems’ products present a much more effective abatement option. Products like concrete or brick simply bounce sound waves off their surface in different directions. Sound Fighter’s products actually absorb or completely eliminate the sound waves that hit them…significantly reducing overall noise.

General structure of equipment
De-coiler
Technical parameters
Width of material sheet: 600—1050mm； Thickness of material sheet: 1.5mm(alufer)/1.0mm(Galvanized sheet)
Inner diameter: φ508mm Range of expanding: ф480-520 mm
Maximum outer diameter: φ1200mm, loading: ≤6T
Motor power:7.5kw Frequency Motor
Speed:0-10m/min,adjustable
Leveler
Working rollers:13+2 Rollers
Feature of structure: after the quenching and tempering, chrome-plating processing, the rigidity, surface roughness of the roller etc. are all enhance greatly; It is composed by the clamping roller and the leveling roller, the clamping roller may the independent control, the leveler has one pair of horizontal guide roller and two pairs of vertical guider roller and easy to
adjust by hand wheel.
Between the leveler and the feeding device, there is optical sensor, sends out the feedback signal to
the control system, the control system sends out the instruction to the frequency conversion motor to
change speed to control the storage quantity of the sheet.Achieves the uninterrupted level goal.

While reflective products like concrete have been the traditional material for noise barrier walls, the advanced absorptive materials found in our sound-absorptive barriers present a much more effective noise abatement option such treatments. Reflective products like block and concrete will only bounce sound waves in various directions. Our barriers actually eliminate the sound waves that hit them, greatly reducing the overall noise.
