These noise barriers walls are build especially along the edge of the many expressways and many other highways. Along roads and expressways , We  have installed many stretches of Noise Barrier Walls bordering residential developments and sensitive areas for noise control and noise reduction to reduce traffic noise pollution especially in areas with houses, schools and residential buildings. Noise pollution along roads in the city, highways and expressways are now particularly bad. The source of noise pollution are caused by engine noises, noise from the tires of cars and heavy vehicles rubbing with the ground. Vehicles noise are particularly bad when buses and trucks ascent slopes or during overtaking. 

MATERIAL USED FOR  NOISE BARRIER WALLS

MATERIAL USED FOR NOISE BARRIER WALLS are the lightweight metal acoustic panels constructed from a combination of Aluminum and Galvanized Iron (GI) sheet. These noise barrier wall panels are held together firmly by galvanized metal "H" beam post and hot dip galvanized for corrosion protection.

Noise barriers can be constructed from many different types of material. Construction materials such as wood, earth, glass, polycarbonate, acrylic, concrete, concrete hollow blocks and concrete hollow panels are commonly used for the construction of noise barrier walls. Such building material have different noise ratings for its sound transmission and sound absorption quality.
