Simulation of the acoustic wave impact on the marine mammal brain, taking the skull geometry into account

This work is aimed at developing a physico-mathematical model to describe the impact of acoustic waves on the marine mammal medulla, taking the skull geometry into account. Directed Green's functions are used as a mathematical apparatus. The skull of a dolphin is conventionally divided into a parietal, occipital, and two temporal planes. Wave penetration is considered taking into account different thicknesses of the cranial bones. The developed model can be used to analyze the behavior of acoustic waves in different areas of the brain. Directional patterns are constructed for the sound pressure of the emitter on the bone and medulla in the corresponding areas of a marine mammal head. In conclusion, an analysis of the results is carried out, and directions for further investigations are outlined.
