Introduction: Noise exposure could result in damage to the organ of Corti and decrease the blood flow of the cochlea, thus resulting in cochlear hypoxia, whereas cigarettes are reported as an ototoxic to the cochlea and as a trigger of cochlear ischemia. Based on that theory, smoking habits and exposure to noise, either alone or together, could cause hearing loss

Objective: To determine the correlation between smoking and Noise Induced Hearing Loss (NIHL)

Method: Analytic with a cross-sectional study

Result:  Of the 122 workers, the proportion of NIHLwas 89.3%, with mild deafness (68.8%) as the most common proportion. We found that there was a significant correlation between types of smokers and severity of hearing loss (p = 0.000). Workers who smoke are likely to experience NIHL1.224 times more likely than non-smokers (PR = 1.224, p = 0.002, CI 95% = 1,077 - 1,392).

Conclusion: There is significant correlation between smoking and noise induced hearing loss
