Metallic Noise Barriers

Metallic Noise Barriers which comprise the great majority of Noise Barriers are generally located at the edge of the road to reflect traffic noise. Some noise is transmitted through the barrier but is slightly less intense than the noise level on the other side of the barrier. The height of these barriers is usually greater than other types. Often traffic noise levels increase for the vehicle occupant.

The most economical choice of Noise control barrier outdoors is the metallic barrier. The main factors that are taken into consideration for an outdoor structure firstly are its ability to perform the intended job in the given environment and have a decent look. The metallic noise barriers are of two types. It can be a one-sided noise reflective barrier or a barrier that has acoustic properties on both sides. The two-sided barrier will deflect sound from either side thereby creating a sound wall. The barrier panels are light in weight as both steel and aluminum are lightweight. This makes it easy to install as well.

A metallic noise barrier could be made of steel, aluminium or stainless steel. Steel is the least expensive material and has many properties that define it as an appropriate material for an outdoor noise control barrier. Aluminium is also known for its durability, lightweightness, and weather resistance.
