Temporal bones are extracted from fresh cadavers, and the condition of only the ear-drum attachment to the temporal bone is made. Then, the dynamical characteristics of the ear-drum of the specimen are measured with a newly developed measuring apparatus. At the same time, applying the impedance theory of the tube to the external auditory canal and the energy method to the ear-drum, the equation corresponding to the output of the apparatus is obtained. Comparing the measurement results and the numerical results, the Young's modulus EE and Damping parameterξE=cE/2 (mEkE) 1/2 are determined to be EE=3.25×108 dyn/cm2 andξE=0.158.
