              perforated   Noise barrier/ soundproof wall/ soundproof fence 

perforated   Noise barrier/  soundproof wall Introduction 

perforated   Noise barrier is also called sound bar rier, soundproof wall due to its great noise absorption property. It is generally made of high density metal sheet resisting over 30db noise through punching, and has louver hole, micro hole, etc.

 perforated   Noise barrier/  soundproof wall Application

• Noise barrier helps in absorbing the noise generating from vehicles on a heavy vehicular traffic area, such as expressway, railway, bridge, urban rail transit noise barrier.
• Noise barrier has proven to be effective in absorbing noise and providing an excellent solution to reduce noise for residential areas near to the busy roads, and also for schools, hospitals.
• Noise barrier can also reduce the mechanical noise, such as the air condition, cooling towers.
