NOISE PROTECTION USING “BROKEN” PROFILE SCREENS

Problem statement. In the cities of Ukraine there are entire systems urban noise sources, namely: road transport, industrial and municipal enterprises, rail transport (trams, railways), air water playgrounds, stadiums sports grounds, etc. Some these sources operate in residential area, some − on its borders. area city, most powerful source noise, which is more common, traffic flows through main streets. At same time a whole system noise. These streets various purposes, parking lots, garages, multi-level interchanges highways, car service stations public buildings structures served by other modes transport. The purpose this article ability to increase effectiveness protection particular situation, without increasing geometric dimensions screen. Conclusions. use screens «broken» profile under certain conditions may be much effective than flat screens. Screens can not only those that directly protect structure, but it different pavilions, canopies used for away from upper surface contours (shops, garages) If, as result calculating screen profile, part will create large tipping moment, possible keep structure balance strengthening foundation. case, you stiffness diaphragms, special extension cables support sloping part, etc., depending specifics specific conditions. reduce height mark highest horizon significantly cost material manufacture.
