Not only does the pier and panel wall is more economical due to decreased wall thickness and continuous foundation is not needed also it is simpler to construct compared with cantilever wall.
The result is an attractive noise barrier wall with the durability and versatility inherent in brick masonry structures.
These boards are nailed to heavy rails which in turn are supported by heavy posts.

The design of highway masonry sound barrier is carry out like pier and panel walls or cantilever wall.
A noise barrier also called a soundwall noise wall sound berm sound barrier or acoustical barrier is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution noise barriers are the most effective method of mitigating roadway railway and industrial noise sources other than cessation of the source activity or use of source controls.
Sound barriers play an important role in controlling the amount of noise that escapes from a noisy area.
