摘　　要：目的:了解健康老人听觉脑干反应特点及建立正常值。方法:选择2002-01/2004-12在山东淄博市收集的社区志愿者以及淄博市社会福利院的职工40名,所有被试者年龄>60岁,认知功能良好,认知功能筛选量表评分为(91.8±7.9)分。应用丹麦电生理仪及Click短声刺激对40名健康老人的听觉脑干反应作了检测,观察额区、中央区和枕区各波的绝对潜伏期和绝对波幅,并比较C3和C4左右脑半球有无差异。结果:40名健康老人全部进入结果分析。①听觉脑干反应基本波形包括波Ⅰ至波Ⅶ7个正相波,波形重现性好。②各波的绝对潜伏期和绝对波幅:额区、中央区和枕区3个区域差异无显著性意义(P>0.05)。③中央区左右半球比较:听觉脑干反应绝对潜伏期及绝对波幅在中央C4和C3区域差异无显著性意义(P>0.05)。结论:健康老人听觉脑干反应不受意识状态的影响,具有较高特异性。AIM： To investigate the characteristics of auditory brainstem response （ABR） in healthy aged people and the standard values METHODS： The ABR was recorded from 40 healthy aged volunteers from communities and employees in Shandong Zibo Society Welfare House, All the subjects older than 60 years had good cognitive function and scores on cognitive function scale were 91.8±7,9, ABR was measured in 40 subjects by using a Dantec Concerto BEAM-SEEG 16 Instrument and Click short stimulation to observe the absolute latency and amplitude in frontal region, central region and occipital region and compare the difference in C3 and C4 regions between the right and left cerebral hemispheres. RESULTS： All the 40 subjects were involved in the result analysis. （1） Waves Ⅰ-Ⅶ were found with good capability of recurrence. ②There were no significant differences in the absolute latency and amplitude of waves among the frontal region, central region and occipital region（P〉0.05）. ③No significant differences were found in the C4 and C3 regions between the left and right cerebral hemisphere（P〉 0.05）. CONCLUSION： The ABR of healthy aged people is stable, and impervious to the variation of consciousness with a higher specificity.
