Ci garette smoking can cause many potentially fatal diseases and worsen others. Numerous studies have shown the relationship between smoking and hearing loss. However, the increase in auditory threshold in high frequency arising from smoking has been very little described. Aim: to compare low and high frequency auditory thresholds among a group of smoking and non-smoking male individuals between 18 and 40 years. Study design: Cross-sectional. Materials and Methods: by means of low and high frequency tonal threshold audiometry we studied 30 male individuals between 18 and 40 years and 30 non-smokers of matching age and gender. Results: auditory thresholds were different between smokers and non-smokers, being worse in the former. Although within normal ranges, auditory thresholds in low frequencies were higher among smokers. In high frequencies we noticed a marked increase in auditory thresholds among smokers. Conclusion: we found statistically significant difference in auditory thresholds in low and high frequencies, among young male individuals, smokers and non-smokers, being worse in the former.

ResumoIntrodução: A audição, sentido que nos permite receber a informação sonora, se apresenta como um dos facilitadores para uma interação social eficaz. Um déficit nessa função acarreta prejuízo no processo comunicativo, devendo ser diagnosticado e tratado precocemente. Atualmente dispomos de meios subjetivos
