Beschreibung
Zusammenfassung:	A cushioning element for use in a vehicle, for example in an aircraft, includes at least one tuned absorber embedded within the cushioning element. The tuned absorber is tuned to absorb noise at a predetermined frequency of at least 20 Hz. A method of providing noise absorption within a cabin of a vehicle includes determining a predetermined frequency of at least 20 Hz of an undesirable noise within the cabin, and configuring an internal structure of a cushioning element to define a tuned absorber tuned to absorb noise at the predetermined frequency, the cushioning element in use being located in the cabin.
