声导纳测试已广泛应用于临床.本研究对多个年龄组的正常耳利用声导纳计进行共振频率和相位角测试,其结果表明 中耳传音系统的劲度因素作用在20～40岁年龄段时较大,随着年龄1增长,其作用逐渐减小并有波动,质量因素作用在50岁以后逐渐开始增强.
Acoustic admittance test has been widely used in clinical.This study of multiple age groups using normal acoustic admittance meter for resonance frequency and phase angle test results show that the middle ear acoustic system stiffness factor in 20 ~ 40 As the age group is older, with the increase of age 1, the effect gradually decreases and fluctuates, and the quality factor gradually begins to increase after the age of 50.
