The skull has a system of vibration with characteristic Eigen-frequencies and oscillation modes. Macereted and non-macereted skulls showed lines of nodes of a typical manner which is specific for the hominides. Specially the mod of vibration of the 2. Eigen-frequency is strongly correlated with the state of the skull. Defined fractures of the base causes the Eigen-frequency shifting in rostral direction. Patterns of fracture, diaphanoscopic and x-ray investigation showed no correlations to the mod of vibration of all the Eigen-frequencies. In the clinical practice this findings give a diagnostic possibility in immediate identification of the fractures and infractures.
