| Abstract: | Objective To study on impact of instable noise i n worker' s hearing loss.Method1456fracturing workers of oil field were randomly selected as study group,other 351workers were slected as contr ols.Other conditions were similar b etween study group and control group.Level of hearing loss was measured under various intensity of nois e in workers with different period of noise exposure.Result High fre-quency of audition was damaged in workers exposed to instable noise for a l ong time,positive rate was 35.1%.Po stitive rate for tinnitus and language frequency was 18.9%and 5.5%,respectively,which was markedly higher compared with control group.Conclusion Hearing loss will progress with the longation of working time and increase of noise int ensity. |
