The capabilities to apply the FEM in hearing re-search field are large: the identification of tissues proper-ties, the definition of the behaviour of hearing elements or even it could improve the clinical surgical intervention. Numerous researchers are focused on hearing improve-ment or understanding problems by working on middle ear or inner ear behaviour. In our work we focused on mechanical properties identification of incus by using micro-CT scanning, per-forming vibrational analysis and finally the FE simula-tions. Contrarily to other researchers we supposed incus bone to be non-homogeneous body and accordingly at-tributed different densities in long and short processes. The non-homogeneity of the long and short processes could be the reason why the incus bone behaviour does not depend simply on degradation level and affected area size. Final-ly, by inverse FE modelling, the Young Modulus was esti-mated.
