An acoustic abatement apparatus for an aircraft includes a layer of material disposed exterior to a fuselage of the aircraft, where the layer of material connects to the fuselage to establish a gap between the layer of material and the fuselage, a flexible container disposed in the gap, and at least one acoustic resonator connected to the flexible container. The at least one acoustic resonator is tuned to a predetermined resonator frequency.
