目的:探讨正常中老年人ASSR与纯音听阈的相关性。方法:给32例正常中老年人分别行0.5kHz,1kHz,2kHz,4kHz ASSR与电测听测试,比较ASSR测试值与纯音听阈的一致性(t检验)与相关性(相关系数的t检验)。结果:不同频率ASSR测试值均数与纯音听阈均数差值为3.00～l0.38dB HL;除左耳0.5kHz
Objective: To investigate the correlation between ASSR and pure tone hearing threshold in normal middle-aged and elderly people. Methods: The ASSR and electrical audiometry tests of 0.5 kHz, 1 kHz, 2 kHz and 4 kHz were performed respectively on 32 normal middle-aged and elderly people. The consistency (t-test) and correlation (t-test of correlation coefficient) . Results: The difference between ASSR test value and pure tone threshold was 3.00 ~ l0.38dB HL at different frequencies. Except the left ear 0.5kHz
