A system and method for regulating pressure inside a vehicle (“cabin pressure”) is disclosed. The system can include a forward gate and an aft gate that can be moved from a closed position to an open position to release cabin pressure in a controlled manner. The forward gate, the aft gate, or both can comprise an interior cavity and one or more permeable surfaces. When open, or partially open, an airflow can be created by a pressure differential between the cabin pressure and the pressure outside the vehicle (“atmospheric pressure”). At least a portion of the airflow can flow through the one or more permeable surfaces and the hollow cavity of the forward gate, the aft gate, or both to promote laminar flow through the gates and into the atmosphere alongside the vehicle (e.g., an aircraft fuselage). In this manner, flow efficiency can be increased and noise reduced.
