Smoking is a public health concern and we are still unsure of its relation with auditory problems.
To study the effects of cigarette smoking in auditory thresholds, in otoacoustic emissions and in their inhibition by the efferent olivocochlear medial system.
144 adults from both genders, between 20 and 31 years of age, smoking and non-smoking individuals were submitted to conventional and high-frequency audiometry, transient stimuli otoacoustic emissions and suppression effect investigation.
smokers presented worse auditory thresholds in the frequencies of 12.500Hz in the right ear and 14,000 kHz in both ears. Regarding the otoacoustic emissions, smokers group presented a lower response level in the frequencies of 1,000Hz in both ears and 4,000Hz in the left ear. Among smokers there were more cases of cochlear dysfunction and tinnitus.
Our results suggest that cigarette smoking has an adverse effect on the auditory system.
吸烟是一个公共卫生关注点，我们仍不确定它与听觉问题的关系。
研究吸烟对听阈、耳声发射及传出橄榄耳蜗中间系统对其抑制的影响。
144 名年龄在 20 至 31 岁之间的成年男女吸烟者和非吸烟者，进行了常规和高频听力测试、瞬态刺激耳声发射和抑制效应研究。
吸烟者在右耳 12.500Hz 和双耳 14.000kHz 的频率上听力阈值更差。在耳声发射方面，吸烟者双耳 1000Hz 和左耳 4000Hz 的反应水平较低。吸烟者中更多出现耳蜗功能障碍和耳鸣。
我们的结果表明，吸烟对听觉系统有不良影响。
