Abstract
This study analyzes the acoustic environment and evaluates the ecological implications of traffic-related noise pollution in two major urban centers of Uzbekistan: Samarkand (eight sites) and Tashkent (four sites). The number of vehicles, maximum sound pressure levels, and equivalent continuous noise levels (Leq) were recorded at standard two-minute intervals. In Samarkand, Rudaki Street near Siyabsky Bazaar had the highest vehicle density (308), with a peak of 84 dB and average Leq of 73 dB (r = 0.635), indicating a moderate positive correlation. In Tashkent, Beruniy Street near Chorsu Hotel recorded 252 vehicles, a peak of 99 dB, average Leq of 85 dB, and a strong correlation (r =0.97). Results show noise levels consistently exceed permissible limits, especially in residential and sensitive areas, causing ecological stress. Findings highlight the urgent need for integrated noise mitigation strategies, including urban planning, traffic regulation, and green infrastructure, aligned with Sustainable Development Goal 11.
