Abstract

The purposes of this study of airport workers were to a) determine the prevalence and symptoms of hearing loss, and b) identify compliance in using hearing protective devices (HPDs) and its relationship with hearing loss. This cross sectional epidemiological study was conducted with 255 noise exposed and 195 non-noise exposed, full time, male workers at a large metropolitan airport in Seoul, Korea. The three measures used were the self administered Occupational Hearing Questionnaire (OHQ), an audiological assessment, and a record review of baseline hearing and noise levels of locations in which the employee worked. The results showed a significant difference in prevalence of hearing loss (more than 25dB) between the noise and the non-noise exposed groups (p < .05). About 60.8% of noise exposed workers reported continuous use of the HPDs. The continuous HPD users had significantly lower rates of hearing loss than the occasional users or non-users. The major symptom for workers with low frequency hearing loss was trouble in communication, whereas tinnitus and fullness in the ear were the most common symptoms for the workers with high frequency hearing loss. The airport workers exposed to excessive noise had a great deal of high f...Continue Reading
