Abstract

|
This study is to evaluate the risk perception of noise of the ground-crews in the Korean airbases who exposed to noise of jet plane. In addition to noise, the perception of other risks such as beef contaminated with dioxin, AIDS, lung cancer, otitis media, shigellosis, driving, drinking, and smoking were also included in the questionnaire of risk perception. Another aim of this study is to diagnose the current hearing conservation program of Korean Air-force.
1148 ground-crews and 231 pilots of 2 airbases participated in the study. The questionnaires of risk perception with visual analogue scale were completed by the participants.
The results are as follows :
1. The perceptions of noise-related risks were high Noise-exposure with protector (ear plug) 3.75, noise-exposure without protector 6.24, occupational disease 6.1, noise-induced hearing loss 5.4. The risk perception of noise-exposure without protector were similar to the risk perception of fatal disease such as AIDS(6.79), or lung cancer(7.22). The perception of drinking, smoking, beef contaminated with dioxin were 5.06, 5.99, and 5.35 respectively. 2. Acknowledgement of necessity of noise measurement, experience of taking a medical advice about ear disease, experience of hearing loss in audiometry, and experience of hearing test showed significant relationship with the perception of noise-related risks.
These variable were also components of hearing conservation program and some of them were able to intervene.
3. It is not effective for the Korean Air-force to maintain the current hearing conservation program. It was showed that Measurement of noise, wearing of hearing protective devices, health education about hearing conservation and noise, and audiologic examination were not performed regularly, and effectively either. The results of this study suggested the necessity of risk communication about noise and activation of effective hearing conservation program in the Korean Air-force.
