摘　　要：目的对正常听力组和聋儿组在不同时间进行两次听性稳态反应测试,并比较两次测试结果的差异程度,从而对ASSR的应用价值及可靠性做出评价。方法分别对7例正常听力年轻人和12例年龄在2～5岁的聋儿在不同时间进行两次ASSR测试,将4个测试频率前后两次的反应阈值进行比较,分析其差异。结果正常组每个测试频率两次结果比较差异无统计学意义,且标准差很小;听力异常组4个测试频率前后两次的反应阈值均有部分病例有一定的差异,程度多为5dB。阈值的这种小幅波动可能是ASSR本身特点所致。结论ASSR测试结果有较高的可靠性。Objective Normal hearing young persons and deaf children received the evaluation with auditory steady-state responses testing at two different times. The responses obtained were then compared for the assessment the retest reliability of the ASSR. Methods 7 normal hearing persons and 12 deaf children were tested with ASSR at two separated times. At the four test frequencies, the results were recorded and compared. Results For the normal hearing group, the differences of the two test results were minimum while the responses of the deaf children showed a maximum difference of 10 dB. These were acceptable fluctuations and the cause may be related to ASSR recording itself. Conclusion The reliability of ASSR is high.
