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