Description
Olumuyiwa Aderinola's study compiled noise level measurements from selected areas within Akure Metropolis, Nigeria. Data was collected using a digital sound level meter at morning, afternoon, and evening intervals over seven days in commercial, residential, and institutional zones. The compiled data were imported into ArcGIS 10.5 for analysis and presentation on noise contour maps.
Use Cases
Generate noise pollution risk maps based on measured decibel levels across land use types.
Compare noise exposure between commercial, residential, and institutional areas based on the described sampling.
Support environmental management and future noise limit regulations based on the identified high-impact areas.
Strengths
Provides specific decibel measurements for named locations, such as 64.3 dB(A) at Sunday bus stop and 38.1 dB(A) on Olowookere street.
Includes quantified risk exposure percentages: 80% of commercial area, 18.7% of residential area, and 36.6% of institutional area exposed to noise pollution.
Limitations
Row count and specific column-level documentation are absent; field semantics must be inferred after download.
