A Comparative Land Use-Based Analysis of Noise Pollution Levels in Selected Urban Centers of Nigeria.

Baloye DO, Palamuleni LG - Int J Environ Res Public Health (2015)

Bottom Line: This study characterized noise pollution levels in Ibadan and Ile-Ife, two urban areas of Southwestern Nigeria that have experienced significant increases in population and land use activities.Findings put the average noise levels in the urban centers at between 53 dB(A) and 89 dB (A), a far cry from the World Health Organization (WHO) permissible limits in all the land use types, with highest noise pollution levels recorded for transportation, commercial, residential and educational land use types.The result of the one-way ANOVA test carried out on the dependent variable noise and fixed factor land use types reveals a statistically significant mean noise levels across the study area (F(3,34) = 15.13, p = 0.000).

ABSTRACT
Growth in the commercialization, mobility and urbanization of human settlements across the globe has greatly exposed world urban population to potentially harmful noise levels. The situation is more disturbing in developing countries like Nigeria, where there are no sacrosanct noise laws and regulations. This study characterized noise pollution levels in Ibadan and Ile-Ife, two urban areas of Southwestern Nigeria that have experienced significant increases in population and land use activities. Eight hundred noise measurements, taken at 20 different positions in the morning, afternoon, and evening of carefully selected weekdays, in each urban area, were used for this study. Findings put the average noise levels in the urban centers at between 53 dB(A) and 89 dB (A), a far cry from the World Health Organization (WHO) permissible limits in all the land use types, with highest noise pollution levels recorded for transportation, commercial, residential and educational land use types. The result of the one-way ANOVA test carried out on the dependent variable noise and fixed factor land use types reveals a statistically significant mean noise levels across the study area (F(3,34) = 15.13, p = 0.000). The study underscores noise pollution monitoring and the urgent need to control urban noise pollution with appropriate and effective policies.

ijerph-12-12225-f004: Daily average noise levels in Ile-Ife.

Mentions: Table 4 shows that the mean, average minimum, and average maximum noise for the morning period in Ile-Ife are 68.59 dB(A), 63.45 dB(A), and 73.4 dB(A), respectively. For the afternoon period, the readings were 68.91 dB(A), 61.9 dB(A), and 74.9 dB(A), respectively, while the mean, average minimum, and average maximum for evening periods were 70.32 dB(A), 65.55 dB(A), and 75 dB(A), respectively. The analysis of daily noise levels for the morning, afternoon, and evening periods in Ile-Ife, reveals that Mondays are the noisiest days, both in the mornings and afternoons. The afternoon readings show a slight difference between the average noise levels on Monday mornings (71.4 dB(A)) and Friday afternoon (71.3 dB(A)). However, Sunday evenings in Ile-Ife are also noisy (Figure 4).
