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.
颅骨有一个具有特征固有频率和振荡模式的振动系统。经过浸软处理和未经过浸软处理的颅骨都显示出具有典型方式的节点线，这是人类所特有的。特别是第二固有频率的振动模式与颅骨状态密切相关。颅底特定骨折会导致固有频率向前移位。骨折模式、透照检查和X射线检查均显示与所有固有频率的振动模式无关。在临床实践中，这些发现为即时识别骨折和骨挫伤提供了一种诊断可能性。
