Original experimental results of the modal analysis (Fig. la) as well as the laserinterferometry and double pulse holorinterferometry measurements (Fig. 1b). after impact loading are presented. The frequency and time dependent transfer functions between selected, anthropologically important points on the skull are studied. The influence of the soft brain tissues on dynamics of the skull was approximately simulated by especially prepared gelatin. The 3D FE model of the human skull (Fig. 2) was developed from the computer tomography (eT) images of the skull investigated experimentally. The FE model incorporates also a model of the interaction of the skull bones with the brain tissue. The developed FE model is verified by the results of the measurements of fundamental frequency-modal characteristics and the transfer functions in time and frequency domain. The FE model enables approximate modelling of the sound transmission in the human skull to hearing organs by the bone conduction in hearing frequency range.
