Understanding the relative impact of environmental noise on health in comparison to other environmental stressors is crucial for public health policy and planning. The main environmental stressor that contributes to cardiovascular morbidity and mortality is air pollution. The associations between environmental noise and air pollution and health are examined in this narrative review of studies. Included were studies of mortality, cognitive outcomes, myocardial infarction, stroke, and hypertension. After adjusting for air pollution, the findings suggest that there are independent effects on cardiovascular outcomes of environmental noise from road traffic, aircraft, and, in fewer studies, railway noise. Air pollution is the primary environmental causes of disability adjusted life years lost (DALYs), according to comparative burden of disease studies. In Europe, environmental noise ranks second in terms of DALYs, and the DALYs it caused were greater than those caused by lead, ozone, or dioxins. In conclusion, environmental noise should be considered an independent contributor to health risk in planning and health impact assessments. It plays a distinct and significant role in ill health in contrast to air pollution.
