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.

The present disclosure makes use of the fact that passengers have ways of adjusting the temperature in their immediate environment or indicating their level of comfort or discomfort and uses information about the passengers' use of the temperature control capabilities in their immediate environment and/or indications of their level of comfort/discomfort as an input to a controller of an environmental control system (ECS) to automatically adjust the ECS supply air temperature set point.

A personal aircraft seat air treatment system may include an air blower, a ventilation output component installed within a passenger compartment, and a treatment component fluidically coupled to the air blower and the ventilation output component.
