Abstract
The invention relates to a viscoelastic damping foam with an adhesive surface for adhesion coupling to vibrating surfaces, for solid-borne sound absorption. The viscoelastic damping foam is obtained through the stoichiometric reaction of a polyisocyanate with at least two polyols of the polyether type which are incompatible with one another.
