摘要
目的 探讨年龄对声导纳测试的声导值和声纳值的影响。方法 采用GSI - 3 3version 2中耳分析仪 ,对 9～ 72岁共 92个耳科正常人按年龄分六组 ,均采用三种频率探测音进行声导值和声纳值检测。结果 使用2 2 6Hz探测音时 ,第Ⅳ组的声纳值分别与第Ⅰ、Ⅱ组的比较 ,其差异有显著性 (P <0 .0 5 ) ,第Ⅱ组的声导值与第VI组的比较差异有显著性 (P <0 .0 5 ) ;使用 678Hz探测音时 ,第Ⅳ组的声纳值分别与第Ⅰ、Ⅱ、Ⅲ、Ⅴ组等各组的声纳值比较差异有显著性 (P <0 .0 5 ) ,第Ⅳ组的声导值分别与第Ⅱ、Ⅵ组等各组的声导值比较差异有显著性 (P <0 .0 5 ) ;使用 10 0 0Hz探测音时 ,第Ⅳ组声纳值分别与第Ⅰ、Ⅱ、Ⅴ组等各组的比较差异有显著性 (P <0 .0 5 ) ,第Ⅳ组的声导值分别与第Ⅰ、Ⅲ、Ⅴ、Ⅳ组等各组的比较差异有显著性 (P <0 .0 5 )。结论 随着年龄的变化 ,鼓膜 -中耳传音系统的质量因素作用的增长较为明显 ,摩擦及粘度因素作用则视声波的频率而异。
Objective To discuss the influence of age using three frequencies probe tone on acoustic conductance and acoustic susceptance of tympanometry.Methods Ninety two people ranging in age from nine to seventy-two years were divided into six groups,and texted using GSI 33 version 2 otoadmittance meter.Results Using 226 Hz probe tone , there was a significant difference of acoustic susceptance among the fourth group and the first groupe,and also the second group( P <0.05) ; there was a significant difference of acoustic conductance between the second group and the sixth group( P <0.05) . Using 678 Hz probe tone , there was a significant difference of acoustic susceptance among the fourth group and the other groups except the sixth group( P <0.05) , there was a significant difference of acoustic conductance among the fourth group and the second group ?the sixth group. Using 1 000 Hz probe tone ,there was a significant difference of acoustic susceptance among the fourth group and the first ?the second ?the third group( P <0.05) , there was a significant difference between fourth group and other groups( P <0.05).Conclusion When age increased , the effect of mass of the tympanum-middle ear transmission has a significant increase . The effect of the stiffness and friction has a change accompanied with the acoustic frequencies .
