Introduction–sound barrier
Sound barrier are also known as soundproof walls.The insertion of facility between the sound source and the receiver causes a significant additional attenuation of the acoustic wave propagation,thereby weakening the noise in a certain area of the receiver,and such a facility is called a sound barrier.

FAQ
1.What is a permanent noise control barrier?
A permanent noise control barrier is a fixed installation designed for the design life of the road or plant, carried on a proper foundation with a structural connection to the ground rather than a ballasted or skid-mounted base. It is engineered for wind load and for long-term exposure.
2.What foundation and post spacing does it need?
Foundation type and post spacing follow the structural design, which takes account of wind load, panel weight, ground conditions and any vehicle impact requirement. On competent ground a cast-in-place concrete footing is common; on bridge decks or where excavation is restricted, a base-plate connection is used instead.
3.What service life can be expected?
Metal systems with a suitable surface treatment are commonly expected to serve several decades, with the finish rather than the steel setting the interval between maintenance. The service life of transparent panels depends on the polymer grade and on UV exposure, and is usually shorter than that of the metal frame they sit in.
4.How does it differ from a temporary barrier?
A permanent barrier is engineered for wind load and durability and is fixed to a foundation, with a design life measured in decades. A temporary barrier prioritises portability and fast removal, so it is lighter, ballasted rather than anchored, and not intended to carry the same acoustic or structural duty.
