Noise barrier walls are built along busy expressways and highways where there is a lot of noise. Busy roads near residential areas cause a lot of noise pollution from the traffic flow. Noise barrier walls help to reduce the level of noise that reaches the residential homes.These noise barrier walls are especially useful in areas near hospitals and schools that may be located near commercial roads or highways with a lot of traffic and noise emancipating. Vehicles make a lot of noise like trucks and busses or two wheelers, noises from tyres screeching or vehicles breaking or even noises from loud horns blaring can be very disturbing and distracting.

Noise barrier walls are also used for railway and metro lines that are running through residential areas or noise sensitive areas. These Noise Barrier walls for highways and outdoors are made from a combination of aluminium and galvanised iron to prevent it from corroding. This material ensures durability and ruggedness. It is weather resistant and gives a good performance outdoors irrespective of the natural weather conditions. The panels of the noise barrier wall are held together with H beam posts which are made of a weather proof non-corrosive galvanised material.

Noise barriers for highways can also be constructed using other material such as concrete, hollow concrete blocks, acrylic, polycarbonate, wood, glass etc. The material used depends on the area of application as well as the client requirement. The noise rating varies depending on the different material used. The material is selected based on the areas it is to be used, the sound transmission and the noise absorption required. We can suggest the best solution regarding material of use and the minimum size of the noise barrier for the required conditions.
