Geoecological assessment of acoustic pollution in the city of Shelekhov (Irkutsk agglomeration)

The work carried out a geoecological assessment of the acoustic pollution of the city of Shelekhov, based on the zoning of the territory according to the noise level. Field surveys were carried out and the number of vehicles registered on the city's road network was calculated. With the help of sound level meters, instrumental measurements were made in the daytime and at night, and the daily course of the distribution of the noise level on the main and secondary roads was plotted. In order to identify the propagation range of noise generated by motor vehicles, the sound pressure levels in the city were calculated for daytime and nighttime using the Ecologist Noise program. The results obtained were compared with the established sanitary standards. The result of acoustic monitoring was the creation of maps of the sound pressure level of the territory. Based on noise pollution maps, a set of measures is proposed to prevent and reduce noise impact on the urban environment.
