Road traffic is the predominant source of noise pollution in urban areas. Despite the enactment of legislation and government efforts to curb vehicular noise, the noise exposure experienced by people in India has continued to rise, primarily due to the rapid increase in vehicular population. This study aims to assess the ambient noise levels in three different zones—commercial, residential, and silent—around Sholinganallur Junction at eight specified time intervals (8:00–9:00 a.m., 9:00–10:00 a.m., 10:00–11:00 a.m., 11:00 a.m.–12:00 p.m., 12:00–1:00 p.m., 1:00–2:00 p.m., 4:00–5:00 p.m., and 5:00–6:00 p.m.).The equivalent noise levels (Leq) In all three zones were found to exceed the permissible daytime limit of 70 dB. Noise descriptors such as L₁₀, L₉₀, Leq, Noise Pollution Level (NPL), and Noise Climate (NC) were analyzed to evaluate the extent of noise pollution caused by heavy traffic. Notably, even the minimum Leq and NPL values recorded were above 60 dB and 65 dB, respectively, highlighting a significant concern regarding urban noise exposure in this area.
