摘　　要：依据纯音听力图的不舒适阈值(uncomfortable level,UCL)进行助听器调试后,感音神经性聋在复合噪声环境下的响度感觉会快速增加,导致明显不适感,该现象在陈旧性感音神经性聋中显得尤为突出。探究导致这种现象发生的原因对助听器舒适度的调试具有指导意义。After hearing aids fitting based on the uncomfortable level（UCL） of pure tone audiograms, sensorineural hearing loss, the loudness in the complex noise environment will rapidly increase to cause significant discomfort, which is particularly prominent in the long-term sensorineural hearing loss. It is instructive for the comfort of fitting hearing aid to explore the cause of this phenomenon.

关 键 词：不舒适阈 复合噪声 临界带宽
