Abstract: The invention relates to a method of making an acoustic product and a novel acoustic product, wherein the acoustic product is made by adhering a facing to a first major surface of an acoustic insulation element by the use of an adhesive and curing the adhesive. The adhesive is an aqueous adhesive composition which comprises



a component (i) in form of one or more oxidized lignins;
a component (ii) in form of one or more cross-linkers;
a component (iii) in form of one or more plasticizers.
