摘要 本文对50例听力正常人的ABR测试结果进行了分析,并结合纯音测听对客观听阈值作出估价。结果表明,各波潜伏期,峰间期在正常范围占受试者总数的96%;纯音0.5K~2KHZ平均听阈,3KHZ听阈与ABR波V反应阈比较相差15分贝。用波V反应阈估价0.5K~2KHZ听力状况,可根据不同年龄酌减10~20分贝,使检测结果更加接近生活语言实际听力阈值。 The auditory brain stem response (ABR)and the obiectve auditory threshold in 50 normal subjects were analyzed. The results show that the latency and interval period in the normal range were96% of those in the total subjects. 15 dB differences were found between the pure-tone 500-2KHzmean auditory threshold, 3KHz auditory threshold and ABR wave V reaction threshold. If 500 -2KHz hearing status was evaluated by the wave V reaction threshold, you can reduce 10-20 dB depending on the different ages so that results could be more close to the actual hearlng threshold in thelife.
