An air induction silencer assembly includes an acoustic interference
member disposed within a conduit. The acoustic interference member is
tuned to acoustically cancel a selected noise energy frequency. An
acoustic absorbing member is also disposed within the conduit. The
acoustic absorbing member converts noise energy within the conduit into
heat energy to attenuate noise energy within the air induction silencer
assembly. The air induction silencer assembly connects to a flexible
conduit that includes an inlet portion, an outlet portion, and a flexible
joint that connects the inlet portion and the outlet portion together.
The flexible joint includes a rolling lobe and a rolling surface. The
rolling lobe moves along the rolling surface when the inlet portion moves
relative to the outlet portion.
