ABSTRACT

A human ear system is divided into three sections namely outer ear, middle ear and inner ear. The human middle ear system is composed of an eardrum, three tiny bones (malleus, incus, stapes) and ligaments. The eardrum is a thin membrane separates the outer and the middle ear system. A hole in the membrane (eardrum) of the middle ear also called as eardrum perforation. The purpose of this research is to show the frequency responses of the human middle ear system with eardrum perforation using the finite element method. The geometric model of human middle ear system with eardrum perforation was obtained from CT scan imaging. Then, the CT scan data was converted to DICOM File. Before exported to finite element analysis software, the data converted to STL file. Finally, the geometrical of human middle ear system was generated by CAD Software using physical properties of components of the human middle ear system with eardrum perforation reported by the previous researchers. Two types of the human eardrum were used in this study namely eardrum perforation and normal eardrum. Then, frequency response analysis had been carried out to show the response on the displacement of stapes of human middle ear system in the frequency range 100 Hz to 10 kHz. As for the frequency responses, the response of human middle ear system with eardrum perforation is lower than normal eardrum due to the decreasing of the mass of human eardrum.
