Abstract
|
|
|
This Study was carried out to measure the noise and to evaluate the prevalence of the noise-induced hearing loss and the hypertension in metal manufacturing workers.
To perform this study 116 workers were tested their hearing level and hypertension.
1. In frequency analysis, the C_5-dip phenomenon occurred around 4000 ㎐.
2. Noise intensity was correlated significantly with hearing loss at 500, 1,000, 8,000 ㎐ (p$lt;0.01).
3. Average hearing loss value by 4-divided method was 32.91±5.60 ㏈.
4. Hearing loss steadily increased to the 10th year and steadily after that at 4000 ㎐.
5. The prevalence of noise-induced hearing loss of 6,027 workers was 1.81 %.
6. The prevalence of hypertension of 116 workers was 11.2 %.
