모 자동차 공장의 소음폭로와 혈압에 관한 연구

This study was carried out to investigate age. noise imcnsity. work period. hearing loss at fre quencies, hypertension and to examine correlation of t~H? total quantity of noise exposure (Dose) and blood pressure (Response) in the auto industry during May 1987--December 1987. To perform this study 65 workers were tested. Results of this study were as follows : 1. In frequency analysis‘ the C5-dip phenomenon occurred around 4000 Hz. 2. Between under of ten years group and over of ten years group. average hearing loss value was statitically significant (P ( 0.05). 3. The prevalence of hypertension of 65 workers was 7.84 %. 4. At 9OdB(A) over and 10 years under and workers in the 20’s group. the total quantity of noise exposure (Dose) and systolic blood pressure (Response) were statistically s&igrave;gnificant (P < 0.05) . 5. At under 10 years of work period group. the total quantity of noise exposure( Dose) and dias tolic blood pressure( Response) were statisticaJly sigmficant (r c 0.234‘ p ι 0.1 ).
