Effect of Chronic Tobacco Smoking on Hearing among Men

چکیده
Cigarette smoking is a well known health problem affecting various body organs. There is a dearth of literature on early changes in auditory functioning at high frequency due to smoking. Hence, the present study aimed to investigate the audiological parameters for 100 chronic smokers. Their results were compared to 50 non smokers. Audiological test battery included conventional pure tone audiometry, extended high frequency audiometry (up to 16 KHz), Distortion Product Otoacoustic Emission (DPOAE) and Transient Evoked Otoacoustic Emission (TEOAE). Results revealed a significant difference between the two groups on conventional and extended high frequency pure tone audiometry. Statistically significant differences were observed between the two groups for DPOAEs and TEOAEs. The results revealed that chronic smokers have impaired hearing at high as well as low frequencies. Smoking may also lead to cochlear dysfunction as revealed by significant difference in OAEs responses between smokers and non-smokers.
