AB A methodology for the development of a finite element numerical model of the tympanic membrane (TM)based on experiments carried out in the time domain on a cadaveric human temporal bone is presented.Using a high-speed digital holographic (HDH) system, acoustically-induced transient displacements of theTM surface are obtained. The procedure is capable to generate and validate the finite element model ofthe TM by numerical and experimental data correlation. Reverse engineering approach is used to iden-tify key material parameters that define the mechanical response of the TM. Finally, modal numericalsimulations of the specimen are performed. Results show the feasibility of the methodology to obtainan accurate model of a specific specimen and to help interpret its behaviour with additional numericalsimulations.
