摘　　要：目的探讨短声诱发听性脑干反应阈与不同听力损失构型人群2～4kHz纯音听阈均值的相关性。方法听力正常组选择正常听力成人10名(20耳)。62例感音神经性聋患者分为平坦型听力损失24耳及陡降型听力损失38耳。陡降型听力损失组38耳再分为四个亚组:1kHz陡降型5耳、2kHz陡降型11耳、4kHz陡降型19耳、6kHz陡降型3耳,均采用短声诱发听性脑干反应记录反应阈及纯音测听记录0.25、0.5、1、2、4、6、8kHz反应阈,记录数据通过SPSSV13.0软件进行分析。结果听力正常组、平坦型听力损失组、1kHz陡降型听力损失组、2kHz陡降型听力损失组2～4kHz纯音听阈均值及click-ABR的反应阈的直线相关系数分别为0.83(P<0.01)、0.94(P<0.01)、0.97(P<0.01)、0.80(P<0.01)。4kHz陡降型听力损失组2～4kHz纯音听阈均值及click-ABR的反应阈的直线相关系数为0.16(P>0.05),6kHz陡降组由于病例较少,差异无统计学意义。结论 click-ABR的反应阈与2～4kHz纯音听阈均值相关性好,但是不能理解为能够用click-ABR的反应阈较精确评估2～4kHz纯音听阈均值。click-ABR的反应阈与2～4kHz纯音听阈均值之差的修正值为36dB,对于正常听力人群和平坦型听力损失人群可较精确评估听阈;对陡降型听力损失人群的听阈评估,ABR的反应阈与2～4kHz纯音听阈均值之差从10dB到70dB。尽管如此,在临床应用中click-ABR的反应阈作为听阈评估仍有其参考价值。Objective To explore the correlation of hearing thresholds using click evoked auditory brainstem response（click-ABR） and pure tone audiometry（PTA） with different auditory configurations. Methods Ten normal hearing adults（20 ears）. Sixty-two cases of sensorineural hearing loss were divided into flat type group（ 24 ears） and steep drop type group（38 ears）. The steep drop type group was further divided into four subgroups：l kHz steep drop type group （5 ears ） ,2 kHz steep drop type group （11 ears） ,4 kHz steep drop type group （19 ears ） ,6 kHz steep drop type group （3 ears）. The response threshold of click-ABR and 0. 25,0. 5,1,2,4,6,8 kHz hearing threshold of PTA were recorded. The recorded data was analyzed by SPSS V13.0. Results The linear correlation of 2-frequency （2, 4 kHz） pure-tone threshold average and the click-ABR response threshold at normal hearing group, flat type group, 1 kHz steep drop type,2 kHz steep drop type coefficients were ： 0. 83 （ P 〈 0.01 ）, 0.94 （ P 〈 0. 01 ）, 0. 97 （ P 〈 0.01 ） ,0. 80 （ P 〈 0.01 ）. 4 kHz steep drop type was ：0.16 （ P 〉 0.05 ）. Because of the 6 kHz steep drop group was fewer, it was no statistically significant. Conclusion The response threshold of click-ABR correlated with 2-frequen- cy（2,4 kHz） pure-tone threshold average, but can not be understood to be able to use the response threshold of click-ABR accurate to assess 2-frequency（2,4 kHz） pure-tone threshold average. The correction value of the differ- ence between the response threshold of click-ABR and 2-frequency（2,4 kHz） pure-tone threshold average was 36 dB. For the normal hearing group and the flat-type group, it can be accurate assessment of hearing threshold. For hearingthreshold assessment of the steep drop type group,the difference between the response threshold of click-ABR and 2- frequency（2,4 kHz） pure-tone threshold average were from 10 dB to 70 dB. Nevertheless, the response threshold of click-ABR as the hearing th
