Title (EN) SOUNDPROOF PANEL
(FR) PANNEAU INSONORISANT
Abstract: front page image
(EN)The invention relates to a soundproof panel having a sandwich structure, which includes two outer walls, a core, and modifying elements that are maintained in a fractal distribution by the core. The panel has an improved trade-off between sound attenuation efficiency and the weight of the panel.
(FR)Un panneau insonorisant à structure sandwich comprend deux parois externes, une âme, et des éléments modificateurs qui sont maintenus par l'âme selon une répartition fractale. Le panneau présente un compromis qui est amélioré entre l'efficacité d'atténuation acoustique et le poids du panneau.
