INTRODUCTION According to the State Statistics Agency of Uzbekistan, the urban population exposed to noise levels exceeding permissible standards reached 65% in 2023, representing a 15% increase since 2018 [1]. This alarming trend correlates with a reported 20% rise in cardiovascular diseases and a 30% increase in stress-related conditions among urban residents in Tashkent and Samarkand over the same period, costing the healthcare system an estimated $50 million annually [2]. Globally, the World Health Organization estimates that environmental noise contributes to 1.6 million healthy life years lost annually in Western Europe alone, with economic costs approaching €40 billion due to noise-related health impacts and productivity losses [3]. Despite growing awareness, significant gaps persist in understanding the long-term, cumulative health impacts of chronic noise exposure, especially in specific regional contexts. Unresolved problems include the lack of standardized methodologies for comprehensive acoustic environment assessment, inadequate integration of health impact data into urban planning, and insufficient financial justification for mitigation strategies that can effectively reduce sound pressure levels (SPL) and protect public well-being. Furthermore, the interplay between environmental noise and socio-economic factors remains underexplored, limiting the development of targeted and equitable exposure limit regulations and interventions. The need for robust, evidence-based research to inform policy and practical solutions for effective noise pollution control and health management has never been more pressing. International scholars have extensively contributed to understanding noise pollution and its health consequences. Fritschi (2014) demonstrated in their study the causal link between chronic transportation noise exposure and an increased risk of ischemic heart disease, proposing a dose-response relationship between decibel (dB) levels and cardiovascular events [4]. M. Basner (2017) conducted comprehensive reviews identifying sleep disturbance and annoyance as primary health impacts of environmental noise, further developing models to quantify the impact of aircraft noise on cognitive performance in children [5]. B. Griefahn (2012) proposed a model illustrating how night-time noise exposure, even below wake-up thresholds, can elevate stress horm ...
