Definition Sound barrier wall are structures used to block off sound, e.g. to protect residential areas from highways and railways, and can be either sound absorbing or sound reflecting.

Description The most important part of the Elematic sound barrier system are sound absorbing panels that can have a sound absorbing capacity in excess of 8 dB. These panels are manufactured using the same methods as for hollow-core slabs, allowing for most of the sound barrier to be made with industrial methods and also offering the benefit of longer spans. In addition, the appearance of sound barriers can be easily be changed with different plant gratings or battening, and individual barriers can be made by changing the color and shape of steel and timber parts.
