EVALUATION OF ACOUSTIC EXPOSITION IN CONDITIONS OF DENSITY URBAN DEVELOPMENT WITH APPLICATION OF GEOINFORMATION TECHNOLOGIES

Dmitrii Koshurnikov

Abstract

In the presented article the approach to establishment of complex noise exposure in conditions of urban territories of a large settlement with application of geoinformation systems is proposed and tested. The main advantages of using geoinformation systems in conjunction with specialized software products used to perform and visualize acoustic calculations are described. Approbation of the proposed approaches was carried out using the example of Perm with the identification of sources of road noise as the main contributor to the overall picture of noise pollution. As a model area, the central part of the city measuring 7 km * 5 km was considered, containing more than 134,000 capital construction objects, accounted for as shielding objects. The performed acoustic calculations were performed in the altitude range from 1.5 to 15 meters with subsequent display of the results in a planar form. The set of planes formed a three-dimensional picture of the noise pollution of the urban settlement, which was displayed using geoinformation systems. The received acoustic results were attributed to the current hygienic standards according to the noise level in the residential area with subsequent visualization in three-dimensional form. Visualization of the results made it possible to distinguish zones of acoustic silence and zones of acoustic discomfort in which a significant part of the urban population lives. The application of geoinformation systems allowed to visualize the picture of noise pollution for the subsequent adoption of management decisions within the city planning.
