Abstract
Noise-induced hearing loss (NIHL) is a major occupational health problem that can be prevented through the use of hearing protection devices (HPDs). The objective of the paper was the accomplishment of a survey ofNoise-induced hearing loss in a small city. A case study design was utilized to identify, describe and evaluate noise sources, exposures and control strategies used by those “high”, “moderate” and “low” risk industry sectors in relation to exposure to noise. The present study involved the pretest data collected as a part of an ongoing hearing protection and cardiovascular disease prevention intervention study.It was found that of the “high risk” industry sectors surveyed, most had mean and median sound levels that were at or above LAeq.8hr85dB.Engineering and construction businesses had the greatest percentage of employees exposed to noise levels above 85dB LAeq.8hr (85%, 83%). Noise exposure in these industries were some of highest recorded in this study. (Median LAeq.8hr range 83.5 – 95dB).From the findings of the present study, it would appear that lack of prioritization of noise exposure and perceptions of the seriousness of NIHL over other things affecting the business are key cultural barriers facing effective noise management at workplaces in developing regions.
