目的 研究儿童短纯音(tone burst)及同侧切迹噪声(notched noise)掩蔽短纯音诱发的ABR反应阈,与短声诱发的听性脑干反应(click-evoked auditory brainstem response,c-ABR)以及40 Hz听觉事件相关电位(40Hz Auditory Event Related Potentials,40Hz AERP)反应阈的关系,以评价这些测试方法 在儿童听力评估中的应用价值.方法 应用SmartEP听觉诱发电位仪在29例(53耳)儿童(男18例,女11例,年龄2月～8岁)中测试短声ABR、短纯音ABR、两种不同强度切迹噪声掩蔽短纯音诱发的ABR(分别定义为c-ABR、tb-ABR、amtb-ABR和bmtb-ABR)及40Hz AERP.结果 (1)tb-ABR、amtb-ABR、bmtb-ABR在2 kHz、4 kHz两个频率的反应阈与c-ABR的反应阈接近,反应阈之间有较好的相关性;(2)tb-ABR、amtb-ABR、bmtb-ABR的反应阈与40Hz AERP的反应阈在0.5、1、2、4 kHz各个频率均接近并有较好的相关性.结论 使用短纯音及同侧切迹噪声掩蔽短纯音诱发的ABR的反应阈预测儿童的纯音行为听阈是可行的.
目的 研究兒童短純音(tone burst)及同側切跡譟聲(notched noise)掩蔽短純音誘髮的ABR反應閾,與短聲誘髮的聽性腦榦反應(click-evoked auditory brainstem response,c-ABR)以及40 Hz聽覺事件相關電位(40Hz Auditory Event Related Potentials,40Hz AERP)反應閾的關繫,以評價這些測試方法 在兒童聽力評估中的應用價值.方法 應用SmartEP聽覺誘髮電位儀在29例(53耳)兒童(男18例,女11例,年齡2月～8歲)中測試短聲ABR、短純音ABR、兩種不同彊度切跡譟聲掩蔽短純音誘髮的ABR(分彆定義為c-ABR、tb-ABR、amtb-ABR和bmtb-ABR)及40Hz AERP.結果 (1)tb-ABR、amtb-ABR、bmtb-ABR在2 kHz、4 kHz兩箇頻率的反應閾與c-ABR的反應閾接近,反應閾之間有較好的相關性;(2)tb-ABR、amtb-ABR、bmtb-ABR的反應閾與40Hz AERP的反應閾在0.5、1、2、4 kHz各箇頻率均接近併有較好的相關性.結論 使用短純音及同側切跡譟聲掩蔽短純音誘髮的ABR的反應閾預測兒童的純音行為聽閾是可行的.

Objective To compare thresholds of auditory brain stem responses(ABR)evoked by tone bursts,and tone bursts ipsilaterally masked by notched noise to thresholds of click-evoked ABR and 40 Hz AERP in children with hearing loss and to determine their values in hearing assessment among pediatric populations.Methods Click-evoked ABRs (c-ABR),ABRs to tone bursts(tb-ABR)and to tone bursts ipsilaterally masked by notched noise of different intensities(amtb-ABR and bmtb-ABR),and 40Hz AERPs were tested using a SmartEP,system in 29 children (53 ears),Of the subjects,18 were male and 11 were female.Results 1)tb-ABR,amtb-ABR and bmtb-ABR thresholds were similar and highly correlated with those of c-ABR at 2 kHz and 4 kHz.2)These thresholds were similar and highly correlated with those of 40Hz AERPs at 0.5,1,2 and 4 kHz.Conclusion ABRs to tone burst and tone burst ipsilaterally masked by notched noise can be used as alternative methods in predicting hearing levels in children.
