The Impact of Sound Pollution on Urban Land Use in Tripoli: A Case Study of Al-Jaraba Neighbourhood, Libya

Abstract

This paper study the environmental noise pollution in mix use and residential district in Tripoli Libya, focusing on its impact on residents. The research involves monitoring the noise level using (day-evening-night (DEN) noise indicator) measured in decibels (dBA) to assess overall annoyance.  Fourteen sampling point were assigned along the four main street bordering the neighbourhood as shown in (Fig 3). In addition, the site divided into twelve zone, monitoring the noise level in the in-centre node (Fig 10).  Measurements conducted during week days and weekends for week in Summer in 2024. The study’s findings indicate that noise levels in the investigated area consistently exceed both WHO guidelines and the standards set by neighbouring countries like Algeria and Egypt for various land-use zones. Specifically, significantly high noise levels were recorded at intersections along Jama Assagga Road, The old-wall Road, and Aljaraba streets, particularly during. Day and evening hours. Moreover, the results show that noise levels in the district exceeded the limits for residential area, mainly near schools and government buildings during the weekday. However, the results dropped to permissible level during night time and on weekends. The survey result concludes that social survey analysis indicates the awareness level of such noise pollution and its impact on the built environment requires broader attention. In addition, the study conclude that the government need to establish regulation and policy to protect public health and wellbeing of the public form noise pollution and set a recommended noise limit according to Land use.
