Introduction: The development of modern automated machines in industries has considerably decreased the physical burden of workers in addition to increasing the productivity of the industries resulting in noise pollution. Noise exposure above the limit value of 90 dB (A) is known to cause temporary hearing loss among exposed workers.
Materials and Methods: Institutional-based cross-sectional study design was employed for a total of 406 study participants using a simple random sampling technique from January 15 to April 30, 2019. The data collection methods were observational checklist and a self-administered questionnaire. The collected data were entered into EpiData software version 4.2 and exported to SPSS software version 21 for analysis. Bivariate and multivariable logistic analyses wwere used to identify the associated factors. Statistical significance was declared using a 95% confidence interval and a p-value of less than 0.05.
Results: A total of 388 study participants were included in the study with a response rate of 95.6%, of which 254 (65.5%) were females. The overall temporary hearing loss among the textile factory workers was found to be 49% with COR=1.53; 95% CI (1.15– 2.03). The workers from the spinning department were 2.38 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI= (1.16– 4.90). Similarly, workers from the knitting department were 3.67 times more likely to develop temporary hearing loss after exiting from work than workers from the dyeing department (95% CI=1.42– 9.47).
Conclusion: The present study demonstrated that the workforce in the spinning and knitting departments of the textile factory had a high prevalence of temporary hearing loss than the workers in dyeing and garment working sections. Therefore, the textile factory should provide hearing protection devices to the workers.
