摘要
目的探讨正常成人短纯音ABR反应阈(tone burst ABR,tb-ABR)与纯音听阈的相关性。方法对34例(68耳)正常成人分别进行0.5、1.0、2.0、4.0kHz纯音听阈和tb-ABR测试,分析其tb-ABR反应阈与纯音听阈的相关性。结果 68耳0.5、1.0、2.0、4.0kHz tb-ABR反应阈分别为:27.43±3.29、25.98±2.76、16.78±2.37、12.42±2.64dB nHL,纯音平均听阈分别为12.23±3.99、11.82±2.56、9.58±3.23、9.92±2.59dB HL;tb-ABR反应阈与纯音听阈在0.5、1.0、2.0、4.0kHz的差值分别为12.13±4.51、11.43±3.66、7.61±2.43、7.17±1.32dB;两者的Pearson相关系数分别为0.69、0.79、0.84、0.89。结论 tb-ABR反应阈与纯音听阈有相关性,tb-ABR具有频率特异性,能更好地反映各频率听力,可用于儿童听力评估。
