Each noise protection screen is a construction that is erected along motorways, large avenues and railway tracks, in order to suppress noise.
Noise protection screens allow you to protect all nearby homes, as well as parks and public transport stops from transport noises. Most often, the installation of such screens is economically justified in the most densely populated areas. Also, such structures protect the population from road dust and debris in case of an accident. Noise protection screens allow you to create a quiet area even in close proximity to the motorway.
According to the protection against noise, such screens are divided into: combined, sound-pressing and sound-absorbing. Depending on the type of screen itself, the materials used to be erected. For sound-absorbing screens, metal perforated sheet and multilayer glass are used. Plexiglas are used to create tinted and transparent screens.
Transparent types of barriers make it possible not to distort the appearance of the city, as well as to significantly improve the safety of the movement of transport due to a good viewing angle and greater highlighting the track. Thanks to the combined screens, in which special transparent inserts are used, the monotony of the route decreases, which can negatively affect the reactions of the drivers themselves.
But, like any other innovations, noise protection screens have several drawbacks. Drivers may have a feeling of limited space on the track, which negatively affects the management of the vehicle and can cause an accident. Also, when installed in such designs of reflective panels, the sound of sound is not reduced, but only changes its directionality, which is capable of creating a directional thread that increases the vibration and stuns flying birds and residents of the upper floors in nearby houses. For efficient noise reduction, screens are required by a height of at least 4 or 5 meters.
