Journal Title: Бюллетень науки и практики - Year 2018, Vol 4, Issue 5
Abstract
The article presents materials characterizing the noise situation of the urban environment, taking into account individual functional zones. The purpose of researches is the assessment of a noise situation in residential and recreational zones of the city. A research object — apart city the environment within the central part of Minusinsk on the sites relating to various functional zones. Residential sites in the centre of Minusinsk are presented by one-story and multistoried houses from two to five floors and the house adjoining areas. Sites of recreations — territories of parks where such species of plants as are prevailing: Populus nigra, Populus laurifolia, Betula, Malus baccata, Acer negundo. On all sites, the tendency to uniform reduction of noise level with an increase in frequency is observed. At the same time, in residential zones, higher levels of noise pressure, than recreation zones are observed. Comparison of the received results with the established standards allows estimating a condition of the urban environment. In general, a noise situation in the side–altars of the central part of Minusinsk favourable, except for certain sites. An exception is the site number 3, relating to the residential development of the city, where the excess of the standard of the sound pressure level by 1.25 times at frequencies of 63 Hz and close to the standard at 250 Hz is recorded. Comparison of the received results with data of earlier conducted researches allows assuming that the main sources of influence in the period of “rush hour” are motor transport and electro installation of municipal services. Thus, these sources of noise can have a negative effect on the general noise situation of the city in certain areas.
