Abstract
OBJECTIVE To investigate the influence of noise on the hearing of the workers with noise exposureand explore the relationship between the hearing damage and the length of noise exposure.METHODS 120 workers who exposed to noise were recruited. Their physical examination including audiometry was done in our hospital from year 2012 to 2014. Hearing loss and the length of noise exposure were detected in all subjects after 2-year's follow-up.The rate of hearing loss between workers with different length of noise exposure was analyzed statistically. RESULTS There were 22 workers who were exposed to noise for 2 years, 43 workers for 3-5 years and 55 workers for 6-10 years. After 2-year's follow up, there were significant differences between the rate of hearing loss and the length of noise exposure at 3,4 and 6 kHz. And the rate of hearing loss at different sound frequency were significantly different statistically. CONCLUSION The relevance ratio of hearing loss in long noise-exposed group was significantly higher than short groups. The hearing damages at 4 KHz were more frequent than other sound frequency.关键词
