Abstract
Noise pollution is one of the most common environmental hazards encountered in everyday
life. The goal of this study was to assess the quantity of noise in the Ponmalai
region of Tiruchirappalli city in southern India and then to use geographic information
systems (GIS) to develop a visualization based on the data. The areas were classified
into three categories: silent, residential and commercial. The Lutron model number
SL4010 was used to measure noise. The mapping was carried out using ArcGIS version
10.3 software (Krigging). To determine the significant differences in noise levels
between morning, noon and evening, a one-way Anova was used, followed by Tukey's
multiple comparisons test. At each location, the vehicle intensity was also assessed.
The findings revealed that the observed sound levels were above the standard limits.
Specifically, during peak hours (morning and evening), the noise level increased
to an extreme. The study found that noise pollution in Ponmalai, India, is primarily
due to increased vehicle movement, sound horns and public gatherings. In conclusion,
recommendations include strict regulations, establishing buffer zones, creating
no-honking boundaries, enforcing heavy vehicle speed restrictions, providing pro-elastic
traffic roadways and implementing noise barriers in sensitive areas.
