Abstract
A duct includes a duct body. The duct body defines an inlet, an outlet, and a channel connecting the inlet and the outlet. The duct body is configured to direct gas flowing within the channel from the inlet to the outlet. The duct body further defines an opening located between the inlet and the outlet. The duct also includes a noise attenuator. The noise attenuator includes sound-absorbing material covering the opening. The sound-absorbing material has an outer face in direct contact with an external environment of the duct body. The sound-absorbing material is configured to dissipate acoustic energy within the channel.
