The level of road noise at Registan Square, Siab Market on Rudaki Street, tram crossing on Rudaki Street, Medical University on Shakhrukh Mirzo Street, Mirzo Ulugbek Street in the city of Samarkand was determined in decibels and compared with the State Standard. In our country, the problem of ecology in the conditions of modern cities is becoming more acute every day, therefore, the study of the urban environment and the reduction of the impact of various man-made resources on it remains a relevant topic. In addition, noise has a negative effect on the auditory and nervous systems of the human body, in addition to increased blood pressure, dilated pupils, gastrointestinal disorders, heart rate and blood pressure, insomnia, and hearing loss. Exposure to high-frequency noise reduces labor productivity by 10-15%, causes hearing failure and deterioration of the general health of a person. Nowadays, city dwellers face the inconvenience of constant and periodic noise at any time of their daily lives: at work, in transport, during leisure and tourist trips, and even during sleep. As was emphasized, the identification of noise sources in the city of Samarkand, the development of measures for their standardization, and the creation of a map of noise sources in the city are of current importance.
