Abstract
An air induction system includes an air duct and an air permeable membrane. The air duct is configured to deliver intake air to an engine. The air duct includes a cylindrical wall defining a bore and an enclosure projecting from an outer radial surface of the cylindrical wall and defining a cavity therein. The cylindrical wall has an opening extending therethrough that enables airflow from the bore to the cavity in the enclosure. The air permeable membrane is configured to cover the opening in the cylindrical wall.

An air induction system comprising:
- an air duct configured to deliver intake air to an engine, the air duct including:
- a cylindrical wall comprising an inner radial surface and an outer radial surface, the cylindrical wall defining a bore;
- and
- an enclosure projecting from the outer radial surface of the cylindrical wall and defining a cavity therein, the cylindrical wall having an opening extending between the inner radial surface and the outer radial surface that enables airflow from the bore to the cavity in the enclosure;
- and
- an air permeable membrane that conforms to at least one of the inner radial surface or the outer radial surface and that is configured to cover the opening in the cylindrical wall.
