Abstract :

 Long term exposure to noise at work causes heå loss. Although countermeasures have successfully reduced noise levels in many industries, noise is still a common occupational hazard, and noise induced heå loss is one of the major occupational diseases worldwide.

Hence the purpose of present study is to find out number of workers with noise induced heå loss in an industry associated with high duration of exposure so that preventive measures can be advised. Material and Methods:  110 male workers selected for the present study, 70 workers were from the exposed group and 40 workers were from the unexposed group. All workers in the industry, with no pre–employment history of heå loss were included in the present study. The ambient noise levels were recorded in manufacturing section, assembly section, paint shop section and office section. The collected data was entered into SPSS (Statistical package for social science) database for analysis. Analysis was done by SPSS software version 10 by using Chi square test and T test. Significance level was set at P<0.05 and considered as significant. Results : The difference in the mean values of duration of service between exposed group and unexposed group was statistically insignificant .Majority of the workers had service duration of more than 10 years. The association between noise induced heå loss and duration of service was found to be statistically significant in exposed group .The association between noise induced heå loss and duration of service was found to be statistically insignificant in unexposed group Conclusion : Workers whose 8 hour TWA exposures exceed 100 dBA should wear double heå protection.  Compulsory intermittent rest periods should be given to the workers. Rest areas with noise levels below 90 dBA should be provided. According to a WHO report, National Programmes for prevention of noise–induced heå loss should be established or strengthened in all countries and integrated with Primary Health Care .
