| 摘 要： | 以500-Hz短纯音作为刺激声,分别测定了20位受试者(9例正常者,11例耳病患者,共40耳)的诱发性耳声发射(EOAE),40-Hz听觉相关电位(40-Hz AERP)和行为反应三项指标的阈值。结果如下:EOAE阈值的主要分布范围在〔20,60〕dB nHL,该范围耳数是其阈值总范围〔15,70)dB nHL耳数的93％;40-Hz AERP阈值主要在〔20,60〕dB nHL,耳数是其阈值范围〔20,90〕dB nHL耳数的95％;行为阈主要在〔20,40〕dB nHL,耳数是其阈值范围〔15,80〕dB nHL耳数的91％,全部受试者有13耳EOAE未引出(正常者3耳,耳病患者10耳),占总测试耳数的33％。三项指标的相关分析表明:EOAE—40Hz AERP,EOAE—行为反应,40Hz AERP一行为反应的r值分别为0.609(0.002

| Abstract: | Evoked oto-acoustic emissions (EOAE) stimulated by 500 Hz tone at a certain range of stimulus levels were recorded in 20 adults(9 normal and 11 abnormal) . No emission could be recorded from 13 (33%) out of all the ears(40), three of them were from three normal adults and ten of them were from five otopathy patients. The EOAE threshold, the thresholds of 40-Hz auditory event -related potential (40-Hz AERP) and psychoacoustical respone were also measured and compared. In this work we found that 93% of EOAE thresholds ranged from 20 to 60 dB nHL, 95% of 40 Hz AERP thresholds ranged from 20 to 40 dB and 91% of psychoacoustical response thresholds ranged from 20 to 40 dB. The correlation analysis showed that the threshold of EOAE was correlated with that of 40 Hz AERP (r =0.607, 0.002
