Abstract
A vehicle seat cover is designed to facilitate acoustic energy absorption by forming in the cover an optimal size and arrangement of perforations based on at target noise frequency range, the perforations allowing the noise to pass through the cover into the interior structure of the seat where the acoustic energy is dissipated in the form of heat.
