Abstract (EN): To better understand the ear functioning, a biomechanical study of the tympanic ossicular chain of the middle ear was made. This chain consists of the tympanic membrane (which has 3 layers), three ossicles (malleus, incus and stapes), six ligaments, tendons and respective two muscles. The objective of this study was to analyze the stresses of the tympanic membrane through images, allowing a comparison of the different frequencies used. A geometric model of the tympanic membrane and ossicles was built through images of Computerized Axial Tomography (CAT). The discretization of this model was done using the finite element method, based on the ABAQUS software. The mechanical properties were obtained from previous work. The results were compared in the dynamic analysis of the tympanic ossicular chain for a frequency range between 100 Hz and 10 kHz, for a sound pressure level of 105 dB SPL, applied on the tympanic membrane. We can observe differences for each frequency in the tympanic membrane.
