Objective The model of base membrane of human cochlea is founded with the finite element analysis(ANSYS), there is certain scope of travel wave and largest amplitude of vibration on the base membrane of human cochlea among every frequency, so that the dynamical response has been researched. Methods This paper discribe the model of human cochlea with the Finite Element which named ANSYS. Results The different frequency is obtained under different situation of the model and different position of human cochlea. Conclusion The different frequency sound cause travel waves from the bottom of the base membrane of human cochlea to the top of the base membrane of human cochlea. The lower vibration frequency is, the further the travel wave transfers, the largest travel wave appears near the top of the base membrane of human cochlea.
