Title (DE) SCHALL ABSORBIERENDES BAUTEIL
(EN) SOUND ABSORBING COMPONENT
(FR) COMPOSANT ABSORBANT LE SON
Abstract: front page image
(DE)Die Erfindung betrifft ein allseitig Schall absorbierendes Bauteil bestehend aus einem Flächengebilde mit darin vorgesehenen Mikrolöchern mit einer kleinsten Querabmessung 0,05 < d < 2 mm, der Dicke t < 10mm des Flächengebildes und mit einem Lochflächenanteil 0,05 < &sgr; < 5 %. Ein wesentliches Element der Erfindung besteht darin, dass das Bauteil gemäß einer erfindungsgemäßen Formel (2) optimiert ist.
(EN)The invention relates to a component, which absorbs sound on all sides and is made of a planar structure with microholes provided therein having a smallest cross-sectional dimension of 0.05 < d < 2 mm, the thickness t < 10 mm of the planar structure and having a hole-surface percentage of 0.05 < $g(s) < 5 %. The invention is characterized in that the component is optimized according to an inventive formula (2).
(FR)L'invention concerne un composant absorbant le son de tous les côtés, constitué d'une structure plane comportant des orifices microscopiques qui présentent une dimension transversale minimale correspondant à 0,05 < d < 2 mm. La structure plane possède une épaisseur t < 10 mm et une proportion d'orifices par rapport à la surface correspondant à 0,05 < $g(s)< 5 %. L'invention est caractérisée, entre autres, en ce que le composant est optimisé selon la formule (2).
