This paper describes software developed based on numerical implementation of algorithms for coupled acoustic – structure interaction. This class of problems implies coupling of the fluid domain, with sound wave propagation, and the domain of solid, which vibrates under the pressure caused by sound waves from the fluid domain. The physical beh...

Wave acoustic equation is implemented and solved using finite element method in PAK solver to simulate propagation of sound waves, that cause oscillations of ear’s components, such as cochlea (part of inner ear). To simulate mechanical behaviour of cochlea, behaviour of fluid in chambers and behaviour of basilar membrane which separates them ...
