This study aims to explore how acoustic waves scatter when interacting with a simplified human body model in a confined space.
Conducted two-dimensional numerical simulations using the µ-diff backscattering algorithm in MATLAB.
Created a human body model composed of circular cylinders with properties resembling different tissue types.
Examined various configurations of PVC inclusions and an absorbing cabin wall.
Analyzed sound pressure level (SPL) distributions at a distance of 1 meter from the body.
Distinct sound pressure levels identified near 160 Hz in the presence of an absorbing wall.
Simulations showed significant variations in acoustic backscatter with different spatial arrangements of concealed objects.
Findings reveal the influence of body composition and enclosure geometry on acoustic wave behavior.
