Spatial Analysis of Environmental Noise and Auditory Health of Abeokuta Residents, Ogun State, Nigeria
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 m2; out of which 33 were randomly selected...

| description | 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 m2; 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 |

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%)
