exposed to noise in hearing abnormalities are different (P < 0。05), and the maximum age group (41 group) had the highest detection rate; ④ There were differences in

hearing abnormalities among the exposed workers with different exposure years (P < 0。05), and the abnormal rates fluctuated with the increase of exposure years。（2） Spearman correlation analysis results shows: ①2011-2014, the hearing loss of noise-expoused workers was related to diastolic blood pressure and systolic blood pressure（r =0。041-0。097，P <0。05）；②Other indexes: hearing loss was not correlated with hemoglobin index, cell index, platelet index, alanine aminotransferase index and average hemoglobin in each year (P > 0。05)。（3）Logistic regression analysis results shows: ①2011-2014, the risk of hearing loss in 16-20 year exposure workers washighe（r   OR2013  =1。362，P＜0。05; OR2014=1。057，P＜0。05); ② The risk of hearing lossin  36-40  year  old  and  ≥41  year  old  in  noise-exposure  workers  is  relatively high（36-40：OR2011   =3。083，P＜0。05；OR2012=1。586，P  ＜0。05；OR2013 =2。437，P＜0。05/≥41：OR2011  =4。416，P＜0。05；OR2012=2。726，P＜0。05；OR2013 =3。629，P＜0。05）。 ③The risk of hearing loss among male noise-expoused workers is higher than that of female noise-expoused    workers Conclusion Sex,  age  and exposure years are influencing factors for hearing loss in noise-exposed workers。
