Abstract

L'invention concerne un élément de construction acoustique qui comprend des cavités d'isolation acoustique présentant une forme constante le long d'un axe parallèle à la surface exposée dudit élément de construction. Au moins une partie desdites cavités comprend une première partie, située à proximité immédiate de la surface extérieure dudit élément, présentant une largeur inférieure à la largeur maximale d'une seconde partie intérieure de la cavité. Ledit élément est caractérisé en ce que: au moins certaines desdites cavités présentent des profondeurs différentes; au moins certaines desdites cavités présentent des volumes intérieurs différents et/ou des formes intérieures différentes; au moins certaines desdites cavités présentent une largeur sensiblement constante sur leur profondeur totale; et au moins certaines desdites cavités sont partiellement ou complètement remplies d'un matériau d'isolation acoustique.
