“…According to the World Health Organization, generally 60-dB (A) sounds can result in temporary hearing impairment and 100-dB (A) sounds can cause permanent impairment (Kiely 1998). The noise levels of Ilorin metropolis are similar to those reported for other cities around the world in Jordan, Spain, Brazil, Greece, and India (Ahmad et al 2006;Amando and Jose 1998;Zannin et al 2002;Georgiadou et al 2004;Panadya 2003).…”

Evaluation and analysis of noise pollution levels have been carried out to determine the level of noise and its sources in Ilorin metropolis. Noise measurements have been done in the morning, at noon, in the evening, and at night to determine noise pollution all over the city. The selected areas of study are commercial centers, road junctions/busy roads, passenger loading parks, and high-density and low-density residential areas. The road junctions had the highest noise pollution levels, followed by commercial centers. The results of this study show that the noise levels in Ilorin metropolis exceeded allowed values at 30 of 42 measurements points. There is a significant difference (P<0.05) in the noise pollution levels and traffic noise index in all the locations. From the measured noise values, a map of noise pollution was developed for Ilorin. Many solutions proposed for noise abatement in the city are set out.

This work is an eye opener to see and understand the importance of the noise map for Nigerian urban areas-as it enables one to know areas that are noisy and the one with low noise.…”

Community noise levels in Ilorin metropolis were measured and analyzed. The noise climate variation was observed to be a function of time due to an increase in population density and other sources of environmental noise. There is increase in the day and night noise levels with growth in population. The noise levels have increased by 2 to 13 dB(A) in the past 20 years in Ilorin metropolis. Statistical analysis shows that the noise level exposure differs significantly from one location to another. High noise levels occur in the daytime at road junctions, followed by commercial centers and passengers loading parks. The noise map developed from this study based on the noise descriptors L D , L N , L DN , TNI, and L NP reveals high noise level exposure at the center of the city where commercial activities and clustered buildings with high population density exist. The noise map provides enough information for technical controls and interim legislation against environmental noise pollution in the metropolis.

“…The outcomes present areal based analysis and visualization of noise data for environmental performance evaluation and planning purposes, with a view to control noise pollution. Noise mapping is a very efficient noise assessment method in urban areas (Panadya, 2003). An environmental noise map is considered as a veritable tool for improving and preserving the quality of the environment with respect to noise pollution.…”

This study assessed environmental noise levels, mapped the spatial pattern at different times of the day and examined the association with morbidity of auditory ailments in Abeokuta metropolis. The entire metropolis was divided into 80 cells (areas) of 1000 m 2 ; out of which 33 were randomly selected for noise levels assessment. Portable noise meter (AR824) was used to measure noise level and Global Positioning System (Garmin GPS-72H) was employed to take the coordinates of the sample sites for mapping. Risk map of the noise levels were produced using Kriging interpolation techniques based on the spatial spread of measured noise values across the study area. Data on cases of hearing impairments were collected from four major hospitals in the city. Data collected from field measurements and medical records were subjected to descriptive (frequency and percentage) and inferential (Mean, ANOVA and correlation) statistics using SPSS (version 20.0). ArcMap 10.1 was employed for spatial analysis and mapping. Results showed mean noise levels range at morning (42.4±4.14-88.2±15.1 dBA), afternoon (45.0±6.72-86.4±12.5 dBA) and evening (51.0±6.55-84.4±5.19 dBA) across the study area. The interpolated maps identified Kuto, Okelowo, Isale-Igbein and Sapon as high noise risk areas. The monitored noise levels varied significantly among the sampled areas at morning, afternoon and evening (p <0.05). Significant correlation was found between diagnosed cases of auditory ailments and noise levels measured in the morning (r=0.39 at p<0.05). Common auditory ailments found across the metropolis included impaired hearing (25.8%), tinnitus (16.4%) and otitis (15.0%) respectively.
