A movable aerodynamic surface for an aircraft is disclosed including a skin having a first skin portion and a second skin portion both extending from the leading edge to the trailing edge and together surrounding an interior from opposite sides, and a stiffener arrangement arranged in the interior and including at least an inboard stiffener in the area of the inboard end and/or an outboard stiffener in the area of the outboard end. At the inboard end between the first skin portion, the second skin portion and the inboard stiffener an inboard cavity is formed, and/or at the outboard end between the first skin portion, the second skin portion and the outboard stiffener an outboard cavity is formed. An acoustic filler arrangement including multiple filler elements is arranged within the inboard cavity and/or the outboard cavity for reducing noise.
