Abstract

Le panneau à absorption acoustique comprend un absorbeur acoustique poreux ayant une surface avant et une surface arrière non plane; un cadre de support à l'intérieur duquel est couplé ledit absorbeur acoustique poreux; un tissu avant acoustiquement transparent fixé sur ladite surface avant dudit absorbeur acoustique poreux; la surface non plane étant configurée de telle sorte que, lorsque le panneau acoustiquement absorbant est fixé à une surface de fixation plane, une chambre comprenant une cavité d'air de profondeur irrégulière pour améliorer l'absorption sonore est définie entre ladite surface arrière non plane et la surface de fixation plane, ladite surface arrière non plane dudit absorbeur acoustique poreux ayant des configurations de surface complémentaires, de telle sorte que de tels deux panneaux acoustiquement absorbants peuvent être empilés les uns sur les autres par couplage de leurs surfaces arrière respectives. Ladite carte peut être directement fixée au cadre de support et à l'absorbeur acoustique poreux, l'absorbeur acoustique poreux étant entouré par le cadre de support.
