Measurements And Analyses Of Noise Levels And Dose At Setraco Quarry Site, Ugwuele, Uturu, Isuikwuato Local Government Area, Abia State, Nigeria
ABSTRACT
The study involved measurements and analyses of noise levels and doses for 14 weeks in setraco quarry ugwuele uturu. The quarry site were divided into three zones, more noise zone (A), medium noise zone (B) and less noise zone (C). The site has about 60-100 workers in different sections of the quarry. Noise dosemeter and noise level meter was used to for the data collected and an Arc-GIS for data analyses which showed the distribution of noise levels in the quarry area. The maximum sound distribution pattern (SD%) is 117.5 SD% which is at the blasting/drilling point while the minimum sound distribution pattern (SD %) is 39.6 SD% which is at the nearest settlement close to the quarrying area. The measured maximum noise levels Lmax were as high as 117.5 dB(A) at the blasting/drilling sites. Noise levels at the facades of the houses in the community and administrative building and noise exposure levels range from 96.0 to 69.8 dB(A), respectively. Most of these results showed an elevation over the control and standard limits with respect to noise levels. These elevations could be attributed to the quarrying activities. Therefore, these quarry workers ought to be protected to avoid much occupation hazard. Longtime exposure to noise sources from the zone A and B will affect the workers psychologically, physically and mentally if strict control measures is not implemented. Workers and individual within zone (C) are mainly affected by noise from vehicular movement and less from other sources of noise from the quarry.
