A Comprehensive Review on the adverse Effect of Traffic Noise

Abstract

Traffic noise is an omnipresent issue in urban environments, significantly impacting public health, property values, and wildlife. This review paper examines the multifaceted adverse effects of traffic noise, focusing on health consequences, economic impacts on property values, and disruptions to animal habitats. Chronic exposure to high levels of traffic noise is linked to a range of health problems, including cardiovascular diseases, sleep disturbances, and impaired cognitive function. Property values in noise-polluted areas often depreciate, reflecting the decreased desirability of such locations. Additionally, traffic noise interferes with animal communication, breeding, and survival, leading to ecological imbalances. This paper also explores the permissible limits for traffic noise as established by various national and international regulatory bodies, with a particular focus on Malaysia. Existing noise regulations and policies worldwide are reviewed to provide a comparative analysis. Through this comprehensive review, the paper aims to underscore the need for stringent noise control measures and highlight best practices for mitigating the adverse effects of traffic noise. Recommendations for future research and policy development are discussed to promote healthier, quieter, and more sustainable urban environments.
