Abstract

The tympanic membrane of the human ear, sometimes called the eardrum, is a thin membrane that separates the outer and middle ears. Perforation of the tympanic membrane might result in longer-lasting hearing loss. This research aims to determine the natural frequencies and mode shape of the tympanic membrane by using the finite element method. The geometric model of the human tympanic membrane was created using CAD software (Solidworks) based on previously published physical parameters reported by other researchers. Then, Hypermesh was used to carry out eigenvalue analysis by imported the geometrical model. Two analysis models were used to compare the dynamic behavior, namely normal tympanic membrane and reconstruction of the membrane, using sliced cartilage myringoplasty. The thickness of the sliced cartilage was varied from 0.05 to 0.5 mm. Finally, the natural frequency and mode shape of reconstruction of the tympanic membrane is the same as normal tympanic membrane when cartilage thickness is 0.4 mm.
