October 7, 2021
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 essentially 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.
