从新鲜尸检病例中取出8块颞骨，检查鼓膜与颞骨的附着情况。然后，利用自行研制的动态特性测量装置，测量了鼓膜的动态特性。同时，将管阻抗理论应用于外耳道，将能量法应用于鼓膜，得到了相应的输出方程。比较测量结果和数值计算结果，确定杨氏模量EE、厚度hE和阻尼比Δ E=cE/2（mEkE）1/2的成人平均值为EE=3.2×107 N/m2，hE=0.1 mm，Δ E=0.2。
Eight temporal bones were extracted from fresh autopsy cases, and the attachment of the eardrum to the temporal bone was examined. Then the dynamic characteristics of the eardrum of the specimen were measured by means of a newly developed measuring apparatus. At the same time, through application of the impedance theory of the tube to the external auditory canal and the energy method to the eardrum, the equation corresponding to the output of the apparatus was obtained. Comparing the measuring result and the numerical result, the adult average values of Young's modulus EE, thickness hE, and damping ratio ξE=cE/2(mEkE)1/2 were determined to be EE=3.2×107 N/m2, hE=0.1 mm, and ξE=0.2.
