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-f002: Map of Ile-Ife.

Mentions: The study areas for this paper are Ibadan, located between latitudes 7°18′′ N and 7°27′′ N and longitudes 3°50′′ E and 3°58′′ E; and Ile-Ife located between latitudes 7°28′N and 7°32′N and longitudes 4°28′ E and 4°34′ E. Ibadan, the third largest city in Africa, with an average population of about 2,550,593, and an average population density of 828 persons per km2 [78] and Ile-Ife, with a projected population of 501,952 [79], are both located contiguously within the same geopolitical zone of the southwestern states of Oyo and Osun, respectively. The two cities also share similar historical developments, as they were both prominent indigenous Yoruba cities that developed outwardly from the Oba’s palace. Similarly, both cities have served as administrative centers at different periods of development of Nigeria. Figure 1 and Figure 2 show metropolitan areas of Ibadan and Ile-Ife, respectively. Climatically, both cities fall under the tropical wet and dry climates (Koppen climate classification, Aw), with a lengthy wet season, which runs from March to October, and relatively constant temperatures throughout the year, between 23 °C and 33 °C during the dry season. At the moment, both Ibadan and Ile-Ife are expressing fast growth, both spatially and socio-economically. The presence of Nigeria’s foremost universities, the University of Ibadan and Obafemi Awolowo in Ibadan and Ile-Ife, respectively, has in no small way contributed to the growth and development of the two study areas. This is evident in the development of residential, commercial, and other socio-economic activities in the areas adjoined to the university campuses.
