应用测定颅顶慢电位(SVP)阈值的方法,研究了23～80岁健康人总计39人70耳的客观听力。结果表明听觉系统的老化在40岁即已开始,50岁后比较明显,并随年龄的增长而愈加明显。
The method of determining the threshold of SVC was used to study the objective hearing of 39 ears and 70 ears in healthy people aged from 23 to 80 years. The results show that the auditory system of aging at the age of 40 has begun, after the age of 50 more obvious, and with age more and more obvious.
