Building An Effective Noise Barrier Wall

So you have decided you need to build a Noise Barrier. What are the important selection criteror to  building an effective noise barrier wall?

1) Select a noise barrier wall material - What material is available, what is the most economical method of construction and how do you construct the noise barrier wall quickly. Noise Barrier Walls can be build from Earth, Timber Panels, Bricks, Metal Panels, Concrete Slabs, Masonry Hollow Blocks, Plastics Sheets such as Polycarbonate or Acrylic sheets and even Glass or other composite material that has some structural rigidity, weather resistance and do not decay and disintegrate easily in rain, hot and cold weather or freezing snow conditions.

2) Design criterior - The effective height and the length of the noise barrier wall.

Simple rule to a good Noise Barrier Wall -

a) It Should be at least four times (4x) the length of the distance between the noise barrier wall and the affected area.
b) The height of the noise barrier wall however depends on the height of the affected area. For effective noise reduction the noise barrier wall should be higher than the affected area or line of sight.
c) The closer the noise barrier wall to the source of the noise the better the results of its attenuation.
