Abstract

Project paper (B.S.(Environmental & Occupational Health)) - Universiti Putra Malaysia, 2014. Background: Noisy environment is anticipated to be present in the population of aircraft maintenance workers in aircraft industry. This study aims to measure noise exposure. hearing threshold level and the factors associated with the hearing impairment among aircraft maintenance workers. An audiometric assessment was carried out to analyze the prevalence of hearing impairment among the workers. Methods: A total of 87 aircraft maintenance personnel participated in a self- administered questionnaire to determine their smoking habits, age, chemical exposure and ototoxic drug exposure of the workers and audiometric test to assess their hearing status. Noise exposure level was measured using noise logging dosimeter to obtain 8-hour Time weighted average (TWA). The data was analyzed using SPSS version 20.1. Results: The aircraft maintenance workers were exposed to high level of noise exposure of more than 85 dB(A) indicating exceeding action level. The prevalence of hearing impairment was 25.3%. Anlong all frequencies tested (500,1000,2000,3000,4000,6000,8000Hz), the percentage of hearing loss is the highest in both right and left ears at frequency 6OOOHz which is 41.41% that represent 36 out of 87 respondents. Besides, the result showed that there is significant relationship (p<0.05) between smoking and hearing status among the aircraft maintenance workers (p = 0.003). However, for other factors such as chemical exposure, age nor ototoxic medication there is no significant relationship which their value is (p>0.05). Conclusion: There is no significant relationship for factors such as age, chemical exposure, ototoxic exposure and noise dose with hearing impairment. There is significant relationship between noise exposure level and chemical exposure (paint stripper) with hearing status in this study. Keywords: Hearing Threshold. Audiometric Assessment, Time-Weighted Average (TWA), Hearing Impairment.
