Vehicle's airtight integrity is a very important factor that greatly affects passenger's habitability. However, when a door is closed, the pressure in the passenger compartment increases due to the vehicle's airtight integrity. That pressurizes the eardrums of the passenger, and makes passenger unpleasant. Thus, in this study, the configurations of air ventilation hasve been investigated to reduce pressure in the passenger compartment. Truck cab is utilized to measure the pressure in the passenger compartment. Various kinds of air ventilations are considered to find out optimized pressure in truck cab when a door is closed.
