What is claimed is: 1. A method for assembling a gas turbine engine assembly, said method comprising: coupling a first wall, a second wall, a third wall, and a fourth wall together to form an enclosure, at least one of the first, second, third, or fourth walls including a first panel including an i
What is claimed is: 1. A method for assembling a gas turbine engine assembly, said method comprising: coupling a first wall, a second wall, a third wall, and a fourth wall together to form an enclosure, at least one of the first, second, third, or fourth walls including a first panel including an inner layer, an outer layer, and a plurality of spaced-apart transverse walls between the inner and outer layers, and a second panel that includes at least an outer layer and a first acoustic material, the first panel is secured against the second panel such that an outer surface of the first panel is flush against an outer surface of the first acoustic material; and positioning a gas turbine engine within the enclosure such that at least a portion of the gas turbine engine is contained within the enclosure. 2. A method in accordance with claim 1 further comprising coupling a plurality of panel stiffening members within the second panel to facilitate providing structural support to the wall. 3. A method in accordance with claim 1 further comprising coupling a plurality of substantially I-shaped panel stiffening members within the second panel to facilitate providing structural support to the wall. 4. A method in accordance with claim 1 further comprising positioning a second acoustic material between at least two of the spaced-apart transverse walls. 5. A method in accordance with claim 1 further comprising coupling the first panel to the second panel using a plurality of mechanical fasteners. 6. An enclosure for an apparatus, said enclosure comprising at least one wall defining at least a portion of an enclosure hollow interior, said wall comprising: an inner panel comprising, in sequence outwardly from the enclosure hollow interior, an inner sheet comprising a plurality of perforations extending therethrough, a plurality of panel stiffening members coupled to said inner sheet, and at least one inner panel sound absorption member comprising a non-metallic sound absorption material positioned between said plurality of panel stiffening members; and an outer panel comprising in sequence inwardly from outside of the enclosure, an outer panel sandwich member comprising non-metallic composite material including spaced-apart first and second walls and a plurality of spaced-apart transverse walls extending between said first and second walls defining hollow chambers therebetween, said outer panel is secured against said inner panel such that an outer surface of said at least one inner panel sound absorption member is substantially flush against an outer surface of said outer panel. 7. An enclosure in accordance with claim 6 wherein said panel stiffening members comprise a plurality of substantially I-shaped panel stiffening members to facilitate providing structural support to said wall. 8. An enclosure in accordance with claim 6 wherein said panel stiffening members are made substantially of a non-metallic composite material. 9. An enclosure in accordance with claim 6 further comprising at least one core fabricated using a porous, non-metallic material, each core positioned substantially within one of said hollow chambers. 10. An enclosure in accordance with claim 6 wherein said inner panel sound absorption member comprises a plurality of layers each made substantially of a non-metallic sound absorption material. 11. An enclosure in accordance with claim 6 wherein said inner panel inner sheet is fabricated using a metallic material, said sound absorption member comprises a plurality of layers each made substantially of non-metallic material, and said the panel stiffening members are made substantially of a non-metallic composite material. 12. A gas turbine engine assembly comprising: an enclosure including a first wall, a second wall, a third wall, and a fourth wall, each said wall comprising: an inner panel comprising, in sequence outwardly from the enclosure hollow interior, an inner sheet comprising a plurality of perforations extending therethrough, a plurality of panel stiffening members coupled to said inner sheet, and at least one inner panel sound absorption member comprising non-metallic sound absorption material positioned between said plurality of panel stiffening members; and an outer panel comprising in sequence inwardly from outside of said enclosure, an outer panel sandwich member comprising non-metallic composite material including spaced-apart first and second walls and a plurality of spaced-apart transverse walls extending between said first and second walls defining hollow chambers therebetween, said outer panel is secured against said inner panel such that an outer surface of said at least one inner panel sound absorption member is substantially flush against an outer surface of said outer panel; and a gas turbine engine positioned within said enclosure. 13. A gas turbine engine assembly in accordance with claim 12 wherein said panel stiffening members comprise a plurality of substantially I-shaped panel stiffening members to facilitate providing structural support to said wall. 14. A gas turbine engine assembly in accordance with claim 12 wherein said panel stiffening members are made substantially of a non-metallic composite material. 15. A gas turbine engine assembly in accordance with claim 12 further comprising at least one core fabricated using a porous, non-metallic material, each core positioned substantially within one of said hollow chambers. 16. A gas turbine engine assembly in accordance with claim 12 wherein said inner panel sound absorption member comprises a plurality of layers each made substantially of a non-metallic sound absorption material.
