A new study has revealed that non-smokers who repeatedly breathe in others’ tobacco smoke are more likely to have some degree of hearing loss.Researchers studied a total of 3307 adults aged between 20 and 69.The degree of hearing loss in each ear was assessed by testing the ability to hear pure tones over a range of frequencies from 500 Hz (low) to 8000 Hz (high).
Men,those who were older,and those with diabetes (糖尿病) were significantly more likely to have high frequency hearing loss.And this was true of those who were former smokers and those who had never smoked.But even after taking account of these factors,both former and passive smoking were associated with damaged hearing.
Former smokers were significantly more likely to have damaged hearing.The prevalence (流行程度) of low to mid frequency hearing loss among this group was 14 percent.And almost half (over 46 percent) had high frequency hearing loss.Although the risk was not as strong among those who had never smoked,almost one in 10 (8.6 percent) had low to mid frequency hearing loss and one in four (26.6 percent) had high frequency hearing loss.
And the stronger findings among former smokers suggested that continued passive smoking in this group,even at low levels,could continue the progression of high frequency hearing loss that began when they were active smokers,say the authors.
“Further research is required to determine whether passive smoking increases the effect of noise exposure and aging on hearing,” they conclude.“If this finding is independently confirmed,then hearing loss can be added to the growing list of health consequences associated with exposure to second-hand tobacco smoke.” The study was published online in Tobacco Control

一项最新研究发现,吸烟者谁一再呼吸在别人的烟草烟雾更有可能有某种程度的听力损失.研究人员研究了共3307岁的成年人之间的20和69.听力损失的程度在每个耳朵是评估测试,能够听到纯音的频率范围从500赫兹到8000赫兹（低）（高）.
人,谁是老年人,和那些有糖尿病（糖尿病）明显更可能有高频听力损失.这是真正的人谁是前吸烟者和从不吸烟者.但是,即使考虑到这些因素,包括前任和被动吸烟是与受损的听力.
前吸烟者明显更可能有受损的听力.患病率（流行程度）中低频率的听力损失在这组百分之14.几乎一半（百分之46）有高频听力损失.但风险并不强,在那些谁从未吸过烟,几乎有10（百分之8.6）已低到中等频率的听力损失和一个四（百分之26.6）有高频听力损失.
和更强的结果之间的前吸烟者被动吸烟的建议,继续在这一组,即使在较低的水平,可以继续发展的高频率听力损失开始时,他们主动吸烟,作者说.
“需要进一步研究,以确定是否被动吸烟增加的影响,噪声暴露与衰老的听证会,”他们总结.“如果这项发现被证实,那么听力损失可以被添加到越来越多的健康后果与接触二手烟草烟雾.”这项研究发表在烟草控制
