In this study, the environmental impact of car noise in the two largest cities of Uzbekistan - Samarkand and Tashkent-was compared in depth. The main objective is to determine how factors such as the level of urbanization of different cities, traffic density, road infrastructure and industrial location affect the level of traffic noise. The study used a modern Assistant SIU 30 v3rt type noise meter at a total of 12 points (8 in Samarkand, 4 in Tashkent) with measurements of car number and noise level at 2-minute intervals of 10-15 minutes per location. During the measurements, the number of cars, maximum and average equivalent noise levels (Leq) were determined. The results showed that noise levels in Tashkent were higher, as well as a very strong correlation (R=0.97) between the number of vehicles and noise. In contrast, in Samarkand, this association is moderately strong (R=0.635), and other environmental and infrastructural factors have also been found to affect noise. The study was also carried out on the basis of international standards, while the results serve as an important basis for ensuring environmental safety, urban planning and the development of anti-noise strategies. The results showed significant differences in noise levels and their relationship to traffic between cities. The analysis confirmed an increase in the permissible noise level in residential areas, public buildings and recreation areas, especially in large cities, taking into account their specific characteristics and factors affecting the noise level. The cited correlation indicators will serve as a statistical basis for the development of noise forecasting and monitoring systems in the future by year. The facts of the article are necessary for the scientific justification of the policy of combating noise in the cities of Uzbekistan. Copyright
