Negative pressure around the front pillar of a vehicle travelling at high speed deforms the door frame in the outward direction. This causes the aspiration noise. Finding a method for the reduction of the resulting air aspiration noise is a goal of this study which analyzes this phenomenon. The method proposed here can be applied to find effective measures to reduce aspiration noise at the early stages of vehicle development.
