Definitions
- the invention relates to a soundproofing element and a noise barrier, especially for roads, highways, railways u. like.
- Noise barriers, noise barriers or noise barriers are everywhere Used where citizens are protected from noise, especially traffic noise should be. Noise barriers can, however, due to the large space requirement not be heaped up everywhere. Just on the edge of roads, highways and railways is the one available for noise control Space often low. In these places can only narrow noise barriers or noise barriers. At noise barriers will be high demands. You need to absorb the sound in the best possible way, weatherproof, robust against falling rocks or vandalism and inexpensive be. At the same time, the visual impression is important. inner city Areas should not be spoiled by concrete walls, and also Motorists and train passengers should not be completely excluded from the environment become. Noise barriers therefore become at least partially transparent executed.
