Systems and methods for sound damping in air conditioning systems in an aircraft is provided. In one embodiment, an air conditioning conduit can comprise a sound-damping wall that at least partially encloses a continuous hollow space for guiding the air. The wall comprises a multilayer design with a core layer and at least one first cover layer. The core layer comprises a sound-absorbing open-pore core material so that the wall shows an acoustic effect. The first cover layer is airtight, is arranged on the external surface of the core layer, and is two-dimensionally connected to the core layer. The two-dimensional connection between the core layer and the first cover layer causes a composite effect in such a manner that the wall is self-supporting and has a structural function in order to be able to transfer mechanically-occurring loads to structural parts of the aircraft.

1. An air conditioning conduit a sound-damping effect for an aircraft, comprising: a sound-damping wall that at least partially encloses a substantially continuous hollow space for guiding the air, the continuous hollow space including an air inlet opening and an air outlet opening, and the continuous hollow space for the conveyance of air directly adjoins the wall, the wall having a multilayer design including:a core layer including a sound-absorbing open-pore core material so that the wall shows an acoustic effect; andat least one first cover layer designed so as to be airtight and arranged on the external surface of the core layer, and laminarily connected to the core layer;wherein the laminar connection between the core layer and the at least one first cover layer causes a composite effect in such a manner that the wall is self-supporting and has a structural function in order to be able to transfer mechanically-occurring loads to structural parts of the aircraft so that the wall also provides a load-bearing effect,wherein the at least one first cover layer is integral with the core layer, and the at least one first cover layer is formed by closing the outer pores of the open-pore core material, the outer pores of the open-pore core material closed by at least one of compressing the outer layer of core material and melting an outer region of the core material, andwherein the core layer comprises an open-pore foam material. 2. The air conditioning conduit of claim 1, wherein the core layer thermally insulates the hollow space vis-à-vis the surroundings. 3. The air conditioning conduit of claim 1, further comprising a second cover layer that is arranged on the internal surface of the core layer, wherein the second cover layer is acoustically transparent. 4. The air conditioning conduit of claim 3, wherein the second cover layer is a vapor barrier. 5. The air conditioning conduit of claim 1, wherein the air outlet opening is an air outlet opening for introducing air into a cabin interior space. 6. The air conditioning conduit of claim 5, wherein the air outlet opening forms a fan-shaped air outlet, and the sound-damping wall is arranged on the lateral surfaces of the fan-shaped air outlet. 7. An airplane comprising: a fuselage structure and a cabin formed within the fuselage; andan air conditioning system including an air conditioning unit and air conduits with air outlet openings, the air conduits conveying the air from the air conditioning unit to the air outlet openings in order to feed the conditioned air into the cabin space, and each of the air conduits further comprises:a core layer including a sound-absorbing open-pore core material; andat least one first cover layer designed so as to be airtight and arranged on the external surface of the core layer, and laminarily connected to the core layer,wherein the laminar connection between the core layer and the at least one first cover layer causes a composite effect in such a manner that the air conduit is self-supporting and has a structural function in order to be able to transfer mechanically-occurring loads to structural parts of the aircraft so that the air conduit also provides a load-bearing effect,wherein the at least one first cover layer is integral with the core layer to form one-piece, and the at least one first cover layer is formed by closing the outer pores of the open-pore core material, the outer pores of the open-pore material closed by at least one of compressing the outer layer of the core material and melting an outer region of the core material, andwherein the core layer comprises an open-pore foam material. 8. The airplane of claim 7, wherein the air conduits form a sound-damping wall that at least partially encloses a substantially continuous hollow space for guiding the air, the continuous hollow space including the air inlet opening and the air outlet opening, and the continuous hollow space for the conveyance of air directly adjoins the wall. 9. The airplane of claim 7, further comprising a second cover layer that is arranged on the internal surface of the core layer, wherein the second cover layer is acoustically transparent. 10. The airplane of claim 9, wherein the second cover layer is a vapor barrier. 11. The airplane of claim 8, wherein the air outlet opening forms a fan-shaped air outlet, and the sound-damping wall is arranged on the lateral surfaces of the fan-shaped air outlet. 12. The airplane of claim 8, wherein the core layer thermally insulates the hollow space.
