Background: Tobacco smoking has been known to affect the human physiology and among the various damaging effects of tobacco, it has been linked with its effect on the sense of hearing. Aim and Objective:This study was designed with the aim of finding the relationship between smoking and hearing loss in various age groups. Materials and Methods:This study included 148 subjects among which 108 were smokers and 40 were age matched non smokers. The smoking history of all the subjects whose ages ranged from 20 to 60 years was taken in detail and their audiometric thresholds were recorded in a sound proof room by a professional audiometrist. The data was analyzed by using appropriate statistical tests. Observation and Results:Smoking was found to be significantly associated with hearing loss. Also, the hearing loss was mainly of the sensorineural type, with the mild type (26-40 dB) of hearing loss being the most common among the smokers.

“…Negley et al [3] reported that carbon monoxide and nicotine in the cigarette reduces oxygen supply to outer hair cells of the cochlea. Previous studies have also shown that high-frequency hearing loss is more common in smokers [7,[17][18][19] . There is evidence suggesting that the cochlear artery, which supplies the basal region of the cochlea, is susceptible to atherosclerotic changes seen in smokers [19] .…”

OBJECTIVE:In this study, an attempt was made to determine the effect of smoking on ultra-high-frequency auditory sensitivity. The study also attempted to determine the relationship between the nature of smoking and ultra-high-frequency otoacoustic emissions (OAEs) and thresholds. MATERIALS and METHODS:The study sample included 25 smokers and 25 non-smokers. A detailed history regarding their smoking habits was collected. High-frequency audiometric thresholds and amplitudes of high-frequency distortion-product OAEs were analyzed for both ears from all participants. RESULTS:The results showed that the ultra-high-frequency thresholds were elevated and that there was reduction in the amplitudes of ultra-high-frequency OAEs in smokers. There was an increased risk of auditory damage with chronic smoking. CONCLUSION:The study results highlight the application of ultra-high-frequency OAEs and ultra-high-frequency audiometry for the early detection of auditory impairment. However, similar studies should be conducted on a larger population for better generalization of the results.

“…Zelman observed that the percentage of hearing loss was greater for smokers in all frequencies. 25 A primary suspected mechanism of hearing impairment associated with smoking is vascular insufficiency of the cochlear end organ. But Drettnor et al could not find any significant difference in hearing loss between smokers and non-smokers.…”

Background: Brainstem auditory evoked responses (BAERs) are electrophysiological investigations have widespread clinical utility in neurology, audiology, neonatology and anesthesiology. BAER responses exhibit a normal variability due to various non-pathologic factors and age is one of the variables suggested to have considerable influence on normal BAE responses. Aging changes in the auditory system may significantly influence the interpretation of the auditory brainstem responses in comparison with younger adults. The present study was undertaken to study the different parameters of brainstem evoked responses in normal subjects and their variations with changing stimulus and subject characteristics among average Indian people. Methods: The test was conducted on 50 neuro-audiologically normal subjects (age-group of 5-60 years) selected from the OPD of ENT Department. Various audio-vestibular tests they were subjected to brainstem evoked response audiometry and responses were studied regarding various parameters of ABR details. An attempt was made to find out a normal range, normative values of various parameters and their variations with respect of their stimulus intensity and subject characteristics. Results: In the present study it was observed that absolute latencies of all waves decreased with increasing stimulus intensity. The mean absolute latency values of all waves were prolonged in male than those of female subjects. The mean inter-peak latency values of I-III, III-V and I-V were also prolonged in male. Effects of change in stimulus rate on absolute latencies of all waves were observed. There were increases in absolute latencies of all waves with increasing stimulus rate. Conclusions: Increased stimulus intensity caused decrease in latency values of all values. Wave V showed lesser degree of variation than the other components. Increase in stimulus rate caused increase in latency of all waves. Wave V showed lesser degree of variation than the other components. BERA can be performed with a wide range of stimulus variations. But what was clear in conclusion was that 60dB SL was the suitable intensity level. Also a wide variety of stimulus rate can be used in combination with either of the stimulus polarity. So any combination of stimulus intensity, rate and polarity may be used for clinical application of BERA. But essence is that there should be a prior adjustment of parameter norms according to subject and stimulus characteristics.
