Title
(EN) ACOUSTIC ARTICLE, ACOUSTIC ASSEMBLY AND METHOD OF MAKING AND USING AN ACOUSTIC ARTICLE
(FR) ARTICLE ACOUSTIQUE, ENSEMBLE ACOUSTIQUE ET PROCÉDÉ DE FABRICATION ET D'UTILISATION D'UN ARTICLE ACOUSTIQUE
Abstract
(EN)
Provided are acoustic articles for damping noise and/or vibration on a substrate. Also provided are acoustic assemblies with such an acoustic article and a primary automotive or aerospace structure. Furthermore, there are provided methods of making such acoustic articles, methods of using such acoustic articles to dampen vibrations on a surface and methods of using such acoustic articles to absorb sound energy.
