The excess of sanitary norms on noise from motor transport in the cities of Irkutsk and Angarsk (Irkutsk agglomeration)

Acoustic pollution is a type of negative impact on the environment. According to the World Health Organization, the increased noise level is the second largest after pollution of the atmospheric air by the environmental cause of health problems in the population of industrial and transport cities. The increase in the number of road transport in the cities of the Irkutsk region leads to an increase in noise levels, its penetration into residential, public and office buildings. The increase in noise is also associated with the construction of new highways, bridges and roundabouts in cities. The article assesses noise pollution in large cities of the Irkutsk region. Observations on the composition and intensity of traffic at major intersections, highways and residential areas were carried out. With help of the sound level meter, noise level measurements were made in the daytime and at night and noise maps of the levels of the urban road network were constructed. The legislative basis for noise regulation in the Russian Federation and the countries of the European Union has been studied. A set of measures is suggested that contributes to reducing the acoustic impact on residents of the cities of the Irkutsk region.
