ACOUSTIC LEVEL IN TOMSK URBAN AREA

Abstract

According to SNiP 23-03–2003 „Noise Protection‟, the urban planning documentation for cities, towns, rural settlements and microdistricts includes the section „Noise Protection‟. Engineers must substantiate their decisions on the acoustic level calculations, which should be made in accordance with the current regulatory documents. The accuracy and simplicity of the acoustic level calculations will allow engineers to make decisions quickly. This paper identifies the best combination of these criteria among the existing and previous methods of detecting noise characteristics. The paper presents a comparison of methods of determining the equivalent acoustic levels at design points in the construction area using the regulatory documents. This analysis is performed for the mainline territories of Tomsk. Three types of cross-sections with different relative positions of the calculated point and the noise source are analyzed. The measurement results are given for the traffic flow and the acoustic level, and the advantages of the utilized methods are described.
