Abstract

Introduction: Hearing loss is one of the most common chronic health conditions and has important implications for the patient’s quality of life. However, hearing loss is substantially underestimated and undertreated. Exposure to excessive noise is the major avoidable cause of permanent hearing impairment worldwide. Noise-induced hearing loss (NIHL) is rated among the top ten work-related problems, and as the most prevalent irreversible industrial disease and the biggest compensable occupational hazard Objective: To determine the prevalence of Noise-induced hearing loss (NIHL) and associated factors among manufacturing factory workers in Nilai, Negeri Sembilan. Methodology: A cross-sectional study was carried out which is designed to ascertain the risk factors and the outcome of interest within the given period of time. Malaysia risk factors namely age, gender, marital status, level of education, income, smoking status, years of services, hobbies and activities, hearing problems, perceived hearing handicaps and noise level of exposure at the workplace were identified and analyzed. The other risk factors such as sociodemographical factors are classified as categorical data and analyzed using the frequency method. Result: Results show that there was a significant association between perceived hearing handicaps with Noise-induced hearing loss since the pvalue was less than 0.05 (p < 0.05). The outcome from the Qhi-square test was conducted since the data is not violated the normality assumption, which is cells less than 20% have expected frequencies > 5. Conclusion: Overall, the study concludes that noise-induced hearing loss shows no significant association between all the risk factors because all the workers are already being provided with proper personal protective equipment of hearing protective devices (HPDs) that could prevent them from being exposed to loud noise at work. Keywords: Noise-induced hearing loss; hearing impairment; manufacturing workers; associated factors.
