Title
(EN) ACOUSTIC PANEL AND ACOUSTIC ENCLOSURE
(FR) PANNEAU ACOUSTIQUE ET ENCEINTE ACOUSTIQUE
Abstract
(EN)
The absorbing acoustic panel of the invention comprises a plurality of grooves (2, 2A, 2B, 2C, 2D) at the frontal face (la) and a plurality of grooves (3, 3A, 3B, 3C, 3D) at the rear face(lb), the grooves (3, 3A, 3B, 3C, 3D) of the rear face (lb) determining a plurality of perforations (4, 4A, 4B) in the panel (1), in the intersection areas with the grooves (2) of the frontal face (la). Said grooves (2, 2A, 2B, 2C, 2D) of the frontal face (la) have a width from 2 and 6 mm, a depth from 5 and 11 mm, and they are spaced a distance from 9 and 14 mm, and said grooves (3, 3A, 3B, 3C, 3D) of the rear face (lb) have a width from 8 and 12 mm and a depth from 5 and 11 mm, and in that: the intersection area of the grooves (3, 3A, 3B, 3C, 3D) of the rear face (lb) with the grooves (2, 2A, 2B, 2C, 2D) of the frontal face (la) determines a perforation rate of the panel (1) equal or lower than 15%, each of the grooves (3, 3A, 3B, 3C, 3D) of the rear face (lb) having a percentage of perforation - free surface equal or higher than 75%, so that said grooves (3, 3A, 3B, 3C, 3D) of the rear face (lb) configure sound absorbing cavities (5,5B) in the panel (1, 1A, 1B, 1C, ID) itself.
(FR)
Le panneau de la présente invention comprend plusieurs gorges (2, 2A, 2B, 2C, 2D) au niveau de la face avant (1a) et plusieurs gorges (3, 3A, 3B, 3C, 3D) au niveau de la face arrière (1b), les gorges (3, 3A, 3B, 3C, 3D) de la face arrière (1b) définissant plusieurs perforations (4, 4A, 4B) dans le panneau (1) dans les zones d'intersection avec les gorges (2) de la face avant (1a), lequel panneau est caractérisé en ce que : lesdites gorges (2, 2A, 2B, 2C, 2D) de la face avant (1a) ont une largeur de 2 à 6 mm, une profondeur de 5 à 11 mm, et sont espacées d'une distance de 9 à 14 mm, tandis que lesdites gorges (3, 3A, 3B, 3C, 3D) de la face arrière (1b) ont une largeur de 8 à 12 mm, et une profondeur de 5 à 11 mm ; et en ce que la zone d'intersection des gorges (3, 3A, 3B, 3C, 3D) de la face arrière (1b) avec les gorges (2, 2A, 2B, 2C, 2D) de la face avant (1a) définit un taux de perforation du panneau (1) inférieur ou égal à 15%, chacune des gorges (3, 3A, 3B, 3C, 3D) de la face arrière (1b) ayant un pourcentage de surface dépourvue de perforation supérieur ou égal à 75% de sorte que lesdites gorges (3, 3A, 3B, 3C, 3D) de la face arrière (1b) forment des cavités (5A, 5B) absorbant le son dans le panneau (1, 1A, 1B, 1C, 1D) proprement dit.
