Noise pollution constitutes a significant concern in urban areas, exerting far-reaching impacts on public health and social well-being. Building on a previous publication on noise pollution levels within the city of Tripoli, Libya, in which noise levels were measured in six distinct highly populated locations, during working days and weekends, and encompassing morning, afternoon, and evening, this analysis is concentrated on only one location-the highway. As expected, the 2nd ring road highway exhibited the highest noise levels among the locations surveyed. These elevated levels underscore the need for targeted noise control measures, particularly the deployment of noise barriers. Consequently, simulation analyzes were performed for different scenarios with noise barrier implementation. The results obtained indicate that the application of these mitigation measures could achieve a significant reduction in noise levels. Noise barriers can effectively reduce noise levels, but depend not only on horizontal distance from the source to the receiver, but also on the receiver’s elevation. Collectively, these findings highlight the critical importance of improving public awareness regarding urban noise pollution, its adverse effects on communities, and the range of applicable mitigation strategies.
