An acoustic damping material includes a binder matrix which includes a bitumen component or a polymer component, and a filler component that includes 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 acoustic damping material may be applied to damping of vibrations and noise in transportation vehicles and white goods, to a vibration and noise damping element including 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.
