Cigarette smoking and auditory effects: Correlation between pack years of smoking and changes in hearing thresholds
Journal Title: Medpulse International Journal of Physiology - Year 2018, Vol 7, Issue 2
Abstract
Background: Cigarette smoking, a well known risk factor for chronic diseases may affect hearing sensitivity. This study aims at studying correlation of pack years of smoking with changes in hearing threshold using pure tone audiometry. Aims and Objectives: To correlate the pack years of smoking with changes in hearing thresholds. Materials and Methods: The study group consisted of 50 cigarette smokers aged between 20-40 years. Study subjects selected were given a questionnaire to collect information regarding their smoking history expressed in pack years. An assessment of auditory thresholds was done for different frequencies by using pure tone audiometer (ELKON-GIGA3) for study group in a sound proof room. The parameters studied in pure tone audiogram are air conduction (AC) and bone conduction (BC) hearing thresholds of both the ears at various frequencies of sound. They are recorded on audiogram chart which depicts the auditory thresholds of the particular ear. Descriptive statistical analysis was carried out on this data. Results: Results showed that there is positive correlation of pack years of smoking with air conduction thresholds of smokers in both right and left ear at all frequencies and also positive correlation of pack years of smoking with bone conduction thresholds were found at higher frequencies (1,2 and4 kHz) in both right and left ear. Conclusion: As the pack years of smoking increase it causes deleterious effects on the auditory thresholds.
