Process for manufacturing an acoustic element and an acoustic element thereof

摘要

The present invention relates to a manufacturing method of acoustic elements and elements thereof, which are based on perforated gypsum plasterboards coated with an acoustic mass. The combination of the present invention, i.e. gypsum plasterboard with a high perforation rate together with an acoustic mass layer, which fills the holes of said gypsum plasterboard, provides a light-weighted and rigid element with excellent acoustic properties in a wide frequency level range.
