Study of the Modeling of Incentive Air Pressure Waves to the Human Ear

Abstract

The variation of interior air pressure of high-speed train will lead to the discomfort of the human ear. In this paper, based on the four principle of modeling assumption, according to the structure of human ear and the mechanical properties of eardrum in the anatomy, the differential function model and transfer function model while the eardrum is under the action of the pressure are build in order to study the relationship between air pressure fluctuation and the comfort degree of the human ear. Under the action of the actual air pressure wave, combined with the interior air pressure comfort index, the simulation and analysis to the model are done, and then the quantitative relationship between the eardrum deformation and the comfort of human ear is built.
