Title (EN) CUSHIONING ELEMENT WITH TUNED ABSORBER
(FR) ÉLÉMENT DE REMBOURRAGE À ISOLANT ACCORDÉ
Abstract:
(EN) 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.
(FR) L'invention concerne un élément de rembourrage destiné à être utilisé dans un véhicule, par exemple dans un aéronef, lequel élément de rembourrage comporte au moins un isolant accordé intégré dans l'élément de rembourrage. L'isolant accordé est accordé pour absorber le bruit à une fréquence prédéterminée d'au moins 20 Hz. Un procédé permettant d'assurer une isolation acoustique dans une cabine de véhicule selon la présente invention, consiste à déterminer une fréquence prédéterminée d'au moins 20 Hz d'un bruit indésirable dans la cabine, et à concevoir une structure interne d'un élément de rembourrage pour délimiter un isolant accordé qui est accordé pour absorber le bruit à la fréquence prédéterminée, l'élément de rembourrage utilisé étant situé dans la cabine.
