Modeling of bone conduction of sound in the human head using hp-finite elements: Code design and verification
چکیده انگلیسی

We focus on the development of a reliable numerical model for investigating the bone-conduction of sound in the human head. The main challenge of the problem is the lack of fundamental knowledge regarding the transmission of acoustic energy through non-airborne pathways to the cochlea. A fully coupled model based on the acoustic/elastic interaction problem with a detailed resolution of the cochlea region and its interface with the skull and the air pathways, should provide an insight into this fundamental, long standing research problem. To this aim we have developed a 3D hp-finite element code that supports elements of all shapes (tetrahedra, prisms and pyramids) to better capture the geometrical features of the head. We have tested the code on a multilayered sphere and employed it to solve an idealized model of head. In the future we hope to attack a model with a more realistic geometry.

Research highlights
► We investigate transmission of acoustic energy through non-airborne pathways to the Cochlea.
► We develop a reliable numerical model for bone-conduction of sound in the human head.
► We built a 3D hp-FE code that supports elements of all shapes to capture geometrical features.
