Abstract
The present invention relates to an air intake duct for an internal combustion engine that is capable of reducing the noise associated with the induction of air. The air intake duct includes an inlet and an outlet as well as an opening in a side wall located between the inlet and outlet. Mounted within this opening is a woven acoustic membrane. The acoustic membrane reduces inlet snorkel noise by dissipating pressure waves in the duct. The woven acoustic membrane is formed from a material that allows sufficient air flow into the air intake duct and also resists water penetration into the air intake duct.
