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
