Abstract

Introduction: Noise-induced hearing loss (NIHL) is a common occupational health concerns, especially among workers who are exposed to high levels of noise on a regular basis. One such group of workers is those who work at airports, where they are exposed to the constant noise of planes taking off and landing. NIHL is a permanent, progressive hearing impairment that can result from exposure to high levels of noise over time. The risk of developing NIHL increases as the level of noise exposure increases and the duration of exposure lengthens. This makes airport workers particularly vulnerable to the condition due to the nature of their work environment. Objectives: To determine the prevalence of noise-induced hearing loss and its associated risk factors among cargo airlines workers at Sultan Abdul Aziz Shah Airport. Methodology: A cross-sectional study was used as the research study design to assess the noise exposure at workplace and to determine the prevalence of noise-induced hearing loss. This study was using a universal sampling where a self-administered questionnaires were distributed to cargo airlines workers based on the inclusion criteria and exclusion criteria. Audiogram test results was used as secondary data to determine the presence of NIHL among the workers. Noise exposure was measured by using Sound Level Meter and Personal Noise Dosimeter. Results: The prevalence of noise-induced hearing loss among ground handling workers at cargo airline is 4%. Findings showed that the minimum level of noise is 54.04 dB(A) located at Ground Handling Service Office and the maximum level of noise is 86.83 dB(A) located at Airside. Besides, there is significant difference (p<0.05) with the usage of personal hearing protection among the ground handling workers. In addition, there is a fairly significant association between noise-induced hearing loss due to noise exposure among workers. The result shows that the Eta value, η of association is 0.363. Conclusion: There is low prevalence of noise-induced hearing loss (4%) and there is an association between usage of personal hearing protection and personal noise exposure level with noise-induced hearing loss. All of the employees are recommended to continuously use PHP correctly while at work in order to preserve their hearing. Keywords: Noise-induced hearing loss; cargo airlines workers; associated factors
