The invention is directed to an acoustic damping material comprising a binder matrix comprising a bitumen component or a polymer component, and filler component comprising at least one solid particulate cellulose-containing filler. The acoustic damping material is suitable for use in damping of undesired vibrations and noise in mechanical structures and components of manufactured articles. The invention is also directed to use of the acoustic damping material for damping of vibrations and noise in transportation vehicles and white goods, to a vibration and noise damping element comprising a damping layer composed of the acoustic damping material, to a method for applying a vibration and noise damping element to a noise emitting surface of a substrate, and to a vibration damped system comprising a substrate and the vibration and noise damping element bonded to a noise emitting surface of the substrate.
