摘　　要：目的研究短音ABR对评估听阈的作用。方法采用特定参数的短音做为刺激音对20名正常人进行了频率特异性ABR检查。观察正常值特点及反应阈与主观听阈之间的差异。结果 20名听力正常人TP-ABR在4k Hz、2k Hz、1k Hz和0.5k Hz时100%可引出Ⅰ、Ⅲ、Ⅴ波。记录Click-ABR与TP-ABR的Ⅰ、Ⅲ、Ⅴ潜伏期、反应阈值。通过采用配对t检验进行统计学分析显示:Clic k-ABR与4k Hz的TP-ABR在I、III、V波潜伏期上均无统计学差异;Click-ABR与2k Hz的TP-ABR在I波潜伏期上有统计学差异,与III、V波潜伏期无统计学差异。Click-ABR与1k Hz、0.5k Hz的TP-ABR在I、III、V波潜伏期上均有统计学差异。TP-ABR的主观阈值与纯音测听间差异无统计学意义。结论 TP-ABR各个频率的听阈情况有一定差距。Objective To evaluate TP-ABRs in determining hearing thresholds.Methods We tested20normaladults with TP-ABRs to determine normative values and the difference between TP-ABR response thresholds and audiometricthresholds.Results The rate of TP-ABR waves I,III and V identification was100%at0.5,1,2and4kHz fromthe20normal adults.The wave I latency showed statistically significant differences between click-ABRs and TP-ABRsat0.5,1and2kHz,but not at4kHz;while latencies of waves III and V showed statistically significant differences fromClick-ABRs at0.5and1kHz but not at2or4kHz.There was no statistically significant difference between TP-ABRand audiometric thresholds.Conclusions The differences between TP-ABR and audiometric thresholds vary across frequencies.
