Abstract
(EN) A method (1000) for manufacturing acoustical elements (100), comprising providing (1002) a first fibre component (102) in the form of mineral wool and a second fibre component (104) in the form of bicomponent fibres having a core with a thermoplastic outer layer, mixing (1004) the first fibre component (102) and the second fibre component (104), for provision of a mixture (1), shaping (1006) the mixture (1) into single layered tile shaped elements (2) whereby the mixture (1) is compressed with a compression ratio to a compressed state, and fixating (1008) the single layered tile shaped elements (2) in the compressed state for obtaining the acoustical elements (100).
(FR) L'invention concerne un procédé (1000) de fabrication d'éléments acoustiques (100), comprenant la mise à disposition (1002) d'un premier composant (102) de fibre sous forme de laine minérale et d'un second composant (104) de fibre sous forme de fibres à deux composants ayant un noyau avec une couche externe thermoplastique, le mélange (1004) du premier composant (102) de fibre et du second composant (104) de fibre, pour obtenir un mélange (1), la mise en forme (1006) du mélange (1) en éléments (2) en forme de tuile monocouche, le mélange (1) étant comprimé avec un rapport de compression à un état comprimé, et la fixation (1008) des éléments (2) en forme de tuile monocouche à l'état comprimé pour obtenir les éléments acoustiques (100).
