A seat assembly includes an external structure, at least one seating support surface, a valve, and at least one air distribution passageway. The external structure has a cavity therein. The at least one seating support surface is configured for contact with an occupant. The valve is disposed within the cavity and is in fluid communication with an external air supply. The at least one air distribution passageway is in fluid communication with the valve and is interposed between the valve and the at least one seating support surface. Air from the external air supply is directed to the seating support surface via the valve and the at least one passageway.

Ventilated vehicle seat systems and methods

Aircraft, environmental control systems, and air diffusers that may be used to create a quiet, comfortable environment within an aircraft cabin are disclosed. The air diffusers include a duct, a grille, and a porous flow conditioner positioned at least partially within an outlet plenum of the duct. The porous flow conditioner is configured to create backpressure and to reduce a velocity of air flowing out of the porous flow conditioner, relative to air flow unaffected by the porous flow conditioner. The porous flow conditioner may be configured to reduce noise generated by air flow through the air diffuser assembly, relative to air flow unaffected by the porous flow conditioner. The porous flow conditioner may be configured to reduce noise generated by air flow downstream of the porous flow conditioner.

Methods and apparatuses for integrated noise control and flow control in an aircraft environmental control system

A method for the automatic removal of speech contamination from an acoustic noise signal. The method includes the steps of: (a) receiving an input acoustic noise signal; (b) automatically detecting speech contamination in the received acoustic noise signal using a VAD; (c) automatically identifying uncontaminated segments of the received acoustic noise signal based upon a decision value output by the VAD; (d) automatically assembling a congruous uncontaminated acoustic noise signal from the identified uncontaminated segments of the received acoustic noise signal; and (e) outputting the congruous uncontaminated acoustic noise signal. Also, systems implementing such a method.
