In order to eliminate or ease the negative effects of the road, railway or air transport, causing excessive acoustic load, the acoustic barriers are applied. In case of the sound sources of linear nature (roads and railways) or of superficial nature, it is impossible to isolate single sources. The only available method is to shield the facilities from the screening sources.

The acoustic barriers form a natural or an artificial barricade, positioned between the noise source and the protected area. Their task is to reduce the intensity level of the sounds reaching the receivers.

The essential factors having influence on the barrier efficiency include the barrier parameters, it means appropriately chosen geometry of the barrier, e.g. its height and length and the properties of the structure, e.g. sound absorbing and sound insulating materials applied in the barrier wall structure.

A significant factor of the acoustic barrier efficiency is position of a barrier against the noise source, position of the observation point and the type of the noise being generated.

The Thermoplast acoustic panels are made of absorption materials which make that some part of the sound wave does not return to the environment but is absorbed by the barrier. The plastic profiles are filled with an absorption material - mineral wool and are reinforced with a metal section. The below table shows better properties of the Thermoplast Acoustic Barriers.

Apart from providing acoustic isolation, the acoustic barriers are a significant architectonic element that may make the surrounding environment more attractive.

The Thermoplast acoustic panels are dyed in mass to obtain any requested colour as per any colour model. They can even be the rainbow colours. The barrier colour may be appropriately matched to the existing colours of the surroundings or natural environment. It is also possible to apply decors imitating wood, other natural raw materials or abstract decors.
