摘要：Abstract: Backgrounds and objectives: Excessive noise pollution is a worldwide occupational health hazard which has considerable social, psychological and physiological impacts, including noise induced hearing loss (NIHL) at higher frequencies. Whilst occupational noise induced hearing loss is entirely preventable if measures are taken, once acquired it is irreversible. Our aim was to evaluate and compare the Auditory functions in subjects exposed to noise with unexposed once (control groups) and to find out the correlation between duration of exposure with observed audiometry parameters. Method: Study was done in 100 food industry workers of them 50 were exposed to noise and remaining 50 were not. Pure tone audiometry was done in all of them and the data obtained was analyzed by Epi info software. Result: It is found that those who were exposed to noise had higher hearing threshold than control with significance. Conclusion: Most food and drink industries have processes which emit high noise levels exceeding the 80dB (A) and 85dB (A) levels which affect their hearing sense adversely, so measures need to be taken to prevent it.
