作者为确定年龄对听力和复杂言语句子识别率下降与听觉诱发电位的相关性,选择纯音听阈不超过30dB(250Hz～4KHz)患者152例,进行研究。结果表明:①老年组在安静条件下合成语句识别率(SSI)比语音平衡词识别率(PB)下降更为明显。②增加短音刺激率引起听觉脑干反应波Ⅴ潜伏期延长的现象在老年人更为明显,这种现象在老年组和年轻组之间差异显著 In order to determine the correlation between age and auditory and evoked potentials in hearing and speech comprehension sentences, we selected 152 patients whose pure tone threshold was not more than 30dB (250Hz ~ 4KHz). The results showed that: (1) The senile speech recognition rate (SSI) of the senile group was lower than that of the phonetic balance word recognition rate (PB). ② increase the rate of short-tone stimulation caused by auditory brainstem response wave Ⅴ latency is more obvious in the elderly, this phenomenon was significantly different between the elderly group and young group
