Noise pollution: a gis-based approach to mapping and assessment

Monitoring noise pollution is crucial for protecting public health and the environment. It provides data and information needed to understand the sources and distribution of noise levels. This paper presents a GIS-based study of noise pollution for an area located in the southwest part of Bucharest, between Mihail Sebastian, Calea 13 Septembrie and Drumul Sarii streets. The values of noise have been recorded by using the Sound Level Meter Lutron -Model SL-4012, in September 2022, for 3 different moments: in the morning, at midday, and in the evening. The results of the analysis have been then used to produce noise maps for each of the three locations. The results showed significant differences in noise levels across different times of the day, with peak levels occurring during daytime hours and early evening in different locations. The study's noise maps provided a clear visual representation of the distribution of noise levels, highlighting areas of concern. The study presents the importance of considering temporal factors in noise mapping and assessment, and the benefits of using GIS tools for this type of analysis.
