This paper presents a parallel infrastructure for reliable numerical simulations of the bone-conducted sound in the human head. We focus on the three dimensional finite element modeling of the acoustics of human head. The human head is modeled with three dimensional tetrahedral finite elements with high polynomial orders of approximation. A fully coupled model based on the acoustic/elastic interaction problem with a detailed resolution of the cochlea region is formulated and solved. The parallel infrastructure is based on the domain decomposition paradigm. The computational mesh is partitioned into multiple sub-domains, and the multi-level direct substructuring parallel solver is utilized to solve the coupled problem.
