A first seat noise control device corrects sound collected by a microphone to sound at a listening position of a user seated on a first seat, generates a cancel sound that cancels, at the first seat, the sound of a second seat audio source output from a second seat speaker by using an adaptive filter, and outputs the cancel sound from a first seat speaker. A second seat noise control device corrects the sound collected by the microphone to sound at the listening position of the user seated on the second seat, generates a cancel sound that cancels, at the second seat, the sound of a first seat audio source output from the first seat speaker using an adaptive filter, and outputs the cancel sound from the second seat speaker.

A stowable travel accessory system that includes a head set and a leg-set for providing full support for the head, the neck and the legs of a passenger. The sets are adapted to be encapsulated together into a compact package. The head set includes an elastic jacket to be dressed on the headrest of the passenger's seat, two cushions for supporting the head, rear straps enable adjustment of the head set to the seats in different aircrafts, and encapsulating the cushions when being folded. The leg-set includes a foldable rigid foot-rest for carrying the weight of the legs, a belt, a buckle for creating a grasping loop from a segment of the belt, into which the cushions are inserted when encapsulated, such that when the strap is stretched, the length of the grasping loop will be reduced to be firmly tightened around the encapsulated head set.

A vehicle system includes a controller that is configured to (a) store a plurality of passenger profiles regarding passengers of a vehicle where each of the plurality of passenger profiles include pre-stored identifying characteristics of a respective passenger associated therewith, (b) acquire passenger identifying data regarding a present passenger in the vehicle, (c) identify a respective passenger profile associated with the present passenger from the plurality of passenger profiles based on the passenger identifying data corresponding with the pre-stored identifying characteristics of the respective passenger profile, (d) control a speaker positioned within the vehicle based at least in part on the respective passenger profile to emit noise-canceling sound waves to generate a noise suppression zone to suppress sound waves perceived by the present passenger, (e) acquire movement data regarding movement of the present passenger within the vehicle, and (f) dynamically adjust the noise suppression zone based on the movement data.
