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.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.

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-f009: Average noise levels and land use in Ibadan.

Mentions: The variation in noise level under different dominant land uses for the three periods of the days of the week were analyzed for each city. Land-use-based distributions of noise in the mornings in Ibadan reveal that residential areas had the least average noise levels of 65.1 dB(A), 66.7 dB(A), and 67.6 dB(A), for mornings, afternoons, and evening, respectively (Figure 9). This range of values falls within the highly risky zones (65–70 dB(A)), which is more than 10 dB(A) above the WHO-recommended daytime residential noise level of 55 dB(A). The average morning, afternoon, and evening noise levels for transportation land use are 73 dB(A), 69.9 dB(A), and 71.15 dB(A), respectively, falling within the highly dangerous zone (75–80 dB(A)). The recorded commercial noise levels for morning, afternoon, and evening, 76.77 dB(A), 73.97 dB(A), and 75.94 dB(A), are falling mostly within the highly dangerous zone (75–80 dB(A)), more than 20 dB(A) higher than the WHO permissible limit of 55 dB(A) (day/night). The industrial areas recorded 73.7 dB(A) and 73.8 dB(A), which were above the WHO recommended noise level at 65 dB(A) (day/night). All the noise levels in the different land-use types exceed the respective recommended average noise levels.
