ESTIMATION OF NOISE POLLUTION OF URBAN ENVIRONMENT FROM AUTOMOBILE TRANSPORT ^{[№ 6 ' 2017]}
In connection with the recent intensive increase in the number of automobile transport, there is an increase in noise pollution of the environment. This leads to the fact that the population living in residential buildings along the roads is in a state of noise discomfort. At the same time, to date no comprehensive studies have been conducted on the noise impact from road transport in Ulan-Ude. The article gives an assessment of noise pollution in Ulan-Ude from automobile transport, which is the most important environmental problem and largely determines the quality of life of the population. The analysis of traffic congestion in Ulan-Ude allowed selecting sections of the street-road network to assess noise pollution. At the selected points, measurements were made on noise from automobile flows during periods of maximum traffic intensity of vehicles and equivalent sound levels were calculated. Comparative analysis of the data obtained in accordance with the requirements of normative and technical documents showed a significant excess of the permissible noise levels. The greatest excess of the standard was found in the most densely populated area of Ulan-Ude. Thus, the noise levels from automobile transport were established for all the motor roads in Ulan-Ude, both according to calculated data and by the results of field measurements. To reduce the noise level, measures are proposed that will reduce the level to normative values, including landscaping along the roads.
