Noise pollution is known to have significant implications for public health and overall well-being. In this study, noise pollution levels were analyzed in selected areas of Tripoli, Libya. The investigation focused on seven distinct locations: Martyr’s square, Algeria square, University hospital, Al-Jalaa hospital, Al-Dehmani park, Al-Tholathaa park, and the Second Ring Road. Noise levels were assessed during working days and weekends across three different time periods: morning, afternoon, and evening. The primary objective was to conduct a thorough evaluation and analysis of environmental noise pollution in Tripoli. This was achieved by employing sound level measurements throughout the seven areas. Additionally, dB mapping has been utilized to visualize the spatial distribution and intensity of noise at the surveyed locations. The initial observations of the study revealed fluctuations in noise levels across the surveyed locations. These variations suggest potential correlations with temporal factors and human activities. This study provides valuable insights into the noise levels in Tripoli, thus creating a comprehensive database for further studies. The identification of elevated noise levels in specific areas and during particular periods underscores the necessity for targeted environmental control measures, such as the implementation of noise barriers. Therefore, a thorough investigation regarding noise barriers should be conducted. In general, the outcome of this study revealed that noise barriers appear to be necessary alongside the Second Ring Road, along with the planting of tall and dense trees, which play an important role in reducing noise in the surrounding areas......................
