Abstract:
A device for reducing a rolling noise of a vehicle having at least one tire, the tire rolling on a roadway on a tire contact patch, wherein the device comprises at least one sound absorption element attached to the vehicle in front of, behind and/or laterally of the tire contact patch in the direction of travel (F) of the vehicle and having at least one resonance frequency and a curved first absorber membrane facing the tire contact patch, wherein the entire first absorber membrane is oriented normally to a direction of sound propagation (S) emanating from the tire contact patch, and the sound absorption element is located at a distance from the tire contact patch which corresponds to a multiple of half a wavelength (λ) assigned to the resonance frequency.
