The 40 Hz AERP threshold of language frequency overestimate the ASSR threshold in 26 ears by 17dB. Conclusion The components of the combinative auditory tests complete each other in expertise of hearing impairment.

• 纯音语频听阈异常耳与40HzAERP语频阈值及ABR比较；纯音语频阈值异常率较40HzAERP及ABR明显高；主、客观听阈明显不符。 26耳40HzAERP与ASSR比较；两者在0.；5kHz、1kHz、2kHz反应阈均值数相关性较好(r=0
