An Assessment of Noise Pollution in Selected Neighbourhoods in Enugu Metropolis, Nigeria

Abstract

Noise is a neglected salient environmental pollutant in some neighborhoods in cities, increasing the risk to human safety and comfort. Noise meter instrument was used to collect data on sound levels in dBA in randomly selected high-density, medium-density and low-density neighbourhoods in Enugu metropolis, Nigeria on work days (MondayFriday) during the morning hours (6:30-10 a.m.), after-noon hours (2.30-6 p.m.) and night hours (7-10 p.m.). T-test was used to make an inference. Results showed that the average sound level for two neighborhoods (Uwani and New Haven) is 62.8 (dBA), while that of Independence Layout and GRA is 50.3 (dBA). Comparing the results with WHO standards showed noise pollution in medium and high density areas, but not in low density areas.
