A sound-absorbing arrangement for an engine nacelle includes a first damping structure that includes a sound-damping honeycomb structure between a perforated inner layer and an outer layer, wherein the first damping structure has a first section and a second section that are arranged behind one another in the axial direction. The arrangement further includes a second damping structure that is formed in a ring-shaped manner and adjoins the first damping structure in the second section of the same in the radially external direction. The second damping structure is formed by multiple hollow chambers that adjoin each other in the circumferential direction, wherein the hollow chambers are formed without a honeycomb structure.
