초록

This Study was carried out to measure the noise and to evalulate the prevalence of the noise-induced hearing loss and the hypertension in metal manufacturing workers. To perform this sutdy 116 workers were tested their hearing level and hypertension. 1. In frequency analysis, the $C_5$-dip phenomenon occurred around 4000 Hz. 2. Noise intensity was correlated significantly with hearing loss at 500, 1,000, 8,000 Hz (p<0.01). 3. Average hearing loss value by 4-divided method was $32.91{\pm}5.60dB$. 4. Hearing loss steadily increased to the 10th year and steadily after that at 4000 Hz. 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 %.
