Noise is one of the most common of all the occupational hazards, more than 9 million workers are exposed to daily average A-weighed noise level of 85 decibels (dBA). These noise level are potentially hazardous to their hearing and can produce other adverse effect as well, there are approximately 5.2 million workers exposed to noise above these levels in manufacturing and utilities, (Boettcher et al, 1987).
The leading source of noise in many cities in the world is the traffic. They are generated by the motors and exhaust system of automobiles, smaller tasks, buses and motorcycles. Thus, Ilorin city (Kwarapoly) has been expanded continuously in all direction in the past decade.
Many significant changes have been subjected to persistent increases in road traffic due to overall increase in property. Hazardous noise level are easily identified and it is technologically feasible to control excessive noise in the vast majority of cases by applying off the shelf technology by redesigning the equipment process or by retrofitting noisy matches or machines. But up till today, nothing was done, (Yilmaz and Ozer, 2005).
Firstly, although many noise control solutions are remarkable expensive others can be costly, especially when the aid is to reduce the noise hazards to level of 85 or 80 dBA. One very important reason for the absence of noise control and hearing conservation programme is that, unfortunately noise is often accepted as a “necessary evil” a part of doing business in inevitable part of an industrial job.
Hazardous noise causes no bloodshed, breaks no bones, but produces no storage looking tissue and if workers can manage to get through the first few days or weeks of exposure, they often feed as through they have “got used” to the noise. But what has mostly likely happening is that they have started to incur a temporary hearing loss which dulls their hearing sensitivity during the work and often subsides during the night,(Dunnet et al, 1991).
The progress of noise induced hearing loss is insidious in that it creeps up gradually over the months and years, largely unnoticed until it reaches handicapping proportions. The reason why hazard of noise are not always recognized is that there is a stigma attached to the resulting hearing impairment.
By people’s demonstration, it is clearly that in article on rehabilitation from noise induced hearing less elsewhere, people with hearing implement are often, thought of as elderly people, mentally people shows and generally incompetent and those at risk of impairment are reluctant to acknowledge either their impairment or the risk for ear of being stigmatized. This is an unfortunate situation because noise induced hearing losses become permanent at as old-age. The time to take preventive step is before the hearing losses begin at as old-age. The time to take preventive step is before the hearing losses begin, (Oyedepo and Saadu, 2003).
AIM: To measure the level of pollution in academic studies and to know the sound level of noise in each area the experiment was taken.
