Annotation Noise pollution is one of the types of negative impact on the environment. It is proved that increased noise level is one of the causes of health problems of people living in cities with developed transport infrastructure. The constant increase in vehicles on city roads and highways leads to a significant increase in noise levels, its penetration into residential areas and residential buildings. The article provides an assessment of noise pollution in the streets of the central district of the city of Chita according to the methodology in accordance with GOST 20444-85. The study involved 43 streets of the central district with the highest congestion. Measurements were taken over 3 months of 2019. The results of experimental studies on measuring noise levels during peak hours on city streets are averaged and presented in tabular form. Field surveys of rolling stock were carried out, its calculation was made. The dependence of the noise load on the traffic intensity at the intersections of residential streets and highways is obtained. A comparison of the obtained experimental data with theoretical and regulatory values for SP 51.13330.2011 is given. A rating of the most polluted streets has been compiled, divided into low-hazardous streets with an excess of less than 5 dB, moderately hazardous from 5 dB to 8 dB and highly hazardous roads with an excess of more than 8 dB. A noise map of the road network of the central district of Chita was built. Recommendations are given on improving the environmental safety of motor traffic and reducing the acoustic impact of noise on residents of the city of Chita
