Aims: The present study was conducted with the aim to study the effect of smoking on hearing threshold and to compare it with non-smokers, also to evaluate relationship between the duration of smoking and quantity of smoking with degree of hearing loss.
Materials and Methods: It was a hospital based Observational study of six months. The study included 30 male smokers of age group between 20-50 years and 30 age matched nonsmoker males visiting ENT OPD without ear complaints. Both smokers and nonsmokers were interviewed by using preformed preliminary
questionnaire. Smoking was ascertained based on questions related to duration of smoking, quantity of smoking. Detailed history, systemic and ENT  xamination was carried out. Pure Tone audiometry was performed. Type and severity of hearing loss was determined.
Results: There was statistically significant difference in hearing thresholds of smokers and nonsmokers (p<0.05). Mild Sensorineural Hearing loss was seen commonly in affected smokers. Severity of hearing loss was seen to be increased with increase in age of subjects and increase in quantity and duration of smoking which was statistically significant.
Conclusion: Smoking increases the risk of hearing loss. It can be prevented by general awareness and early screening in smokers.
