Abstract (EN): The human middle ear is composed by three ossicles, ligaments and muscles tendons. These muscles (tensor tympani and stapedius) have a protection action of the inner ear, avoiding that loud sounds can be harmful. The behavior of these muscles is studied in this work, looking for the correct influence on the biomechanics of the middle ear. A model of the eardrum and the ossicles, based in images of Computerized Tomography (CT), was made (Gentil et al. 2009). The discretization of this 3D solid model was done using the ABAQUS program. Using the Hill model, the simulation of these muscles was made and the results are compared considering passive and active behavior.
