Abstract
Ventilation systems, aircraft, and silencers are disclosed herein. An aircraft includes a ventilation system. A ventilation system includes first and second air flow sources configured to generate first and second air flows, a silencer, a first conditioning vent, and a second conditioning vent. A divider spans an interior dimension of the housing to define a first cavity and a second cavity, where the divider restricts substantially all mass flow between the first cavity and the second cavity in the housing. First and second silencer tubes have porous portions disposed in the respective cavity and are operatively coupled with the respective air flow source to receive the respective air flow. First and second conditioning vents are operatively coupled with the respective silencer tubes to direct the respective air flows to a conditioned volume.
