Abstract
A method for manufacturing acoustical elements, includes providing a first fibre component in a form of mineral wool and a second fibre component in a form of bicomponent fibres having a core with a thermoplastic outer layer, mixing the first fibre component and the second fibre component, for provision of a mixture, shaping the mixture into single layered tile shaped elements whereby the mixture is compressed with a compression ratio to a compressed state, and fixating the single layered tile shaped elements in the compressed state for obtaining the acoustical elements.
