Moreles Física, Astronomía y Matemáticas Tympanum membrane forced semi malleus system membrane vibrations A numerical simulation of the dynamical properties of the tympanic membrane is presented. A simple and different simulation of thevibratory patterns of the coupled system of the tympanum-malleus have been assessed by proposing the modeling of the tympanum throughthe vibrations of a forced elastic membrane, whereas the effect of the manubrium is introduced through a forced semi-membrane. Wepropose the superposition of these waveforms as a model for describing the vibrations of the coupled system of the tympanum-malleus. Bothwaveforms have analytical representations leading to simple computations. The results of the simulation for the vibrational mode (1,1) showan amplitude for the membrane larger than those for the handle of the malleus. The maximum amplitude obtained was around 1 ¹m, at a testfrequency of 2 kHz. Also, level curves corresponding to the simulated vibrational modes were obtained. The numerical model presented canbe easily handled to change input parameters, such as sound pressure and frequency. Also, other situations such as the conical shape of thetympanum or some asymmetries could be considered 2008 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57054209 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
