Method for producing a sound absorbing panel

Abstract

Method for producing a sound absorbing panel including the step of providing a predetermined amount of cellulose fibres. Cellulose fibres have an average length between 0.5 mm and 5 mm, preferably between 1.3 mm and 2.5 mm. The method further includes a step of soaking the cellulose fibres in a water basin to form a pulp and a step of depositing the pulp on a moulding die. The method further includes a step of pressing said the pulp in order to cause at least a partial removal of the water contained making a fibre mat. The method also includes a step of drying the fibre mat so as to cause evaporation of the water remained in the fibre mat making the sound absorbing panel.
