Acoustic Screen System

The contemporary agglomerations require extended transport infrastructure. As the network of motorways, expressways, ringroads and railways is developed, the standard of life of the inhabitants also gets improved. However, an increase in the intensity of road traffic exerts a negative impact on the people and the natural environment. Noise is one of the most noxious factors. An effective way to neutralize the harsh sounds is the noise isolation by means acoustic screens.

The acoustic panels of the ASS have very good sound insulation parameters. The porous structure of the leca pebbles constitutes an effective trap for sounds, causing their partial absorption. At the same time, the surface of the panels which is shaped specifically in the shape of a wave weakens and disperses the sound waves in different directions. Owing to good sound insulation parameters, the ASS panels are used to attenuate the road and railway arteries with great traffic intensity and noise.
