A high frequency attenuating device for an air flow induction system of a vehicle employing a thermoformed fibrous mat of any shape that fits robustly inside the duct. The dissipative nature of the fibrous mat helps in achieving broadband attenuation in the high frequency regime. The ability to manufacture the fibrous mat into any shape helps with restriction, targets different attenuation bands, and makes it more feasible to manufacture, Hybrid solutions are possible when combined with low frequency perforated silencers or high frequency QWT arrays injection molded onto them.

Method of making an acoustic automotive HVAC and AIS duct with a particle fiber slurry
Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such products so as to allow large scale implementation.

An adaptive air intake joint for an internal combustion engine comprising a molded elastomeric duct body having standing ribs constructed and arranged to provide a continuous and sufficient contact force across the face of a joint of an adjoining duct body. A clamp secured to the duct causes the ribs to provide a continuous and sufficient contact force across a seal surface, eliminating the need for constant tension clamp and improving the air intake joint seal to prevent leakage that is especially common in cold environments.

The present invention relates to an air intake duct (20) for an internal combustion engine that is capable of reducing the noise associated with the induction of air. The air intake duct (20) includes an inlet (22) and an outlet as well as an opening (28) in a side wall located between the inlet (22) and outlet. Mounted within this opening (28) is a woven acoustic membrane (1). The acoustic membrane (1) reduces inlet snorkel noise by dissipating pressure waves in the duct (20). The woven acoustic membrane (1) 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 (20).
