Abstract : Transportation represents a fundamental pillar of a nation's economic and overall growth. While its importance cannot be overstated, it also brings about adverse effects on the environment and human health, with noise pollution being one such negative consequence. This research is centered on examining the relationship between traffic density and fluctuations in noise levels. The study took place in the Kpakungu area of Minna city. Noise levels were measured using a sound level meter, and traffic counts encompassed various vehicle types, including two-wheelers, three-wheelers, four-wheelers, buses, and trucks. The findings revealed that the average noise level stood at 77dBA, exceeding the permissible standards established by Nigeria's environmental regulations enforcement agency. The study highlights that an increase or decrease in the number of vehicles does not necessarily lead to a corresponding rise or fall in noise levels. This lack of direct correlation arises from various factors such as traffic flow, horn usage, lane discipline, unauthorized parking, and the diverse mix of vehicles on the road. Minna city's traffic is characterized by heterogeneity, and a lack of adherence to lane discipline often leads to congestion, resulting in frequent horn honking. Consequently, traffic noise levels do not consistently align with traffic counts, and they may exhibit erratic fluctuations due to the aforementioned factors.

Keywords : Traffic Noise, Leq, Heterogeneous, Traffic Flow, Noise Level, Distance.
