Environmental assessment of the noise pollution within the settlements of Ivano-Frankivsk suburban area

Abstract

The aim of the work is to study the noise pollution of Ivano-Frankivsk suburban area on the basis of experimental measurements of noise levels within suburban settlements, analysis of their compliance with regulations and development of noise maps. To assess the noise pollution in suburban settlements, a network of 45 observation points was built in areas of different purposes (in the area of transport infrastructure, production area, area of housing (manor) and public buildings,) in the villages of Yamnytsia, Uhryniv, Kluziv. On a spatial scale, the study area reached 12 km². A portable professional noise meter PCE-322A-ICA, which belongs to class 2 and meets the requirements of the state standard of Ukraine DSTU EN 61672-1:2017, was used to measure noise pollution. Sound level was measured in dBA. Evaluation of measurement results is carried out by comparing the actual indicators with the normative ones approved by the current sanitary norms for residential and industrial areas. For a visual graphical representation of the distribution of noise levels in the study area, noise maps were developed with isolines of sound levels in the field in dBA and with an interval of 5 dBA. The LA sound levels at the points belonging to the traffic flow zone were 63-75 dBA, the maximum LAmax sound levels were 65-77 dBA. Given the permissible sound levels for the nearest protected objects and the distance to them, it can be claimed that the noise level in them will meet the norm. At the observation points located along the perimeter of the production area of IvanoFrankivskcement PJSC, the LA sound levels were 41-59 dBA, the maximum LAmax sound levels were 43-60 dBA. As all points are located within the SPZ of PJSC Ivano-Frankivskcement and maintain a sufficient distance to residential buildings, the impact of industrial noise of this enterprise on the surrounding settlements will not be observed. At the observation points in the area of residential (manor) and public buildings, the greatest differences in the fluctuations of sound levels were observed. LA sound levels and maximum LAmax sound levels were: at points with fluctuations up to 6 dBA LA = 52-56 dBA, LAmax = 55-58 dBA, at points with fluctuations of 16-18 dBA LA = 63-69 dBA, LAmax = 71-78 dBA, at points with fluctuations of 32-35 dBA LA = 69-73 dBA, and LAmax = 86-89 dBA. After evaluating these results it can be concluded that they comply with the norms (allowable LA = 55 dBA, LAmax = 70 dBA for daytime), which apply to residential and public buildings at points without significant fluctuations in noise levels. At other points, exceedances were observed mainly due to high values of maximum sound levels caused by local noise sources from the time of measurements
