Development of a methodology for assessing the impact of vehicles on the acoustic environment

Abstract

Currently, the population of cities is in constant acoustic discomfort, both in production and transport, and in everyday life. Noise sources in cities are diverse. The reason for noise in cities can be mechanical engineering, light and construction industries, while the main source of noise is transport. Its share is 70-80% of the total background noise transmitted through the atmosphere. On major highways, the noise level is 85-92 dB with a maximum sound pressure in the frequency range of 400-800 Hz. In an industrial city, a high percentage of freight transport on highways is common. An increase in the total traffic flow of trucks, especially heavy trucks with diesel engines, leads to an increase in noise levels. Therefore, the development of methods to reduce the noise impact of various man-made sources on the environment of urban areas has become urgent. According to the developed method, you can determine the noise level near the city's roads.
