Abstract
A method for adjusting a vehicle seat includes activating a pump at a selected speed from a number of selectable speeds to inflate a first bladder and adjusting an inner chamber within a sound dampening assembly that is fluidically coupled between the first bladder and the pump. The inner chamber is adjusted to cancel at least one primary frequency generated by the pump that varies with the selectable speeds thereof.
