Title
(DE) VERFAHREN ZUR HERSTELLUNG VON AKUSTISCHEN ELEMENTEN
(EN) A METHOD FOR MANUFACTURING ACOUSTICAL ELEMENTS
(FR) PROCÉDÉ DE FABRICATION D'ÉLÉMENTS ACOUSTIQUES
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),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 tile shaped elements (2) whereby the mixture (1) is compressed with a compression ratio to a compressed state, andfixating (1008) the tile shaped elements (2) in the compressed state for obtaining the acoustical elements (100).
