What is claimed is: 1. A chamber comprising: a base member configured to support a compressor; a cover member coupled to said base member and forming an inner volume between an inner surface of said cover member and said based member to house the compressor therein, said cover member including a first chamber volume isolated from said inner volume, a pair of side members configured to cover the compressor and a two-piece cap member having an integrally formed first locking mechanism; and a first sound absorbing material located within said first chamber volume. 2. The chamber according to claim 1, further comprising isolating members located between feet of the compressor and the base member to isolate the chamber from the compressor. 3. The chamber according to claim 1, wherein one of said base member and said cover member is formed of a material having a mass density sufficient to produce a transmission loss of greater than 10 dB for a sound frequency between 100 and 1000 Hz. 4. The chamber according to claim 1, wherein said cover member is formed from a thermoset material. 5. The chamber according to claim 1, wherein an air gap is located between the compressor and an inner wall of said cover member, a first acoustic impedance being formed by said air gap and a second acoustic impedance being formed by said inner wall. 6. The chamber according to claim 1, further comprising a strap configured to hold the side members together. 7. The chamber according to claim 1, wherein one of said side members includes an integrally formed second locking mechanism configured to couple to said first locking mechanism. 8. The chamber according to claim 7, wherein said first locking mechanism includes one of a concave surface and a convex surface and said second locking mechanism includes the other of said concave surface and said convex surface. 9. The chamber according to claim 1, wherein said cap member defines a cavity filled with a second sound absorbing material. 10. The chamber according to claim 1, wherein said cap member defines a thermally activated check valve. 11. The chamber according to claim 1, wherein said base member defines a cavity filled with a second sound absorbing material. 12. The chamber according to claim 1, wherein said first sound absorbing material is an aggregate. 13. The chamber according to claim 12, wherein said aggregate is at least one of sand and slag. 14. The chamber according to claim 1, wherein said first sound absorbing material is a fluid. 15. The chamber according to claim 14, wherein said fluid is at least one of glycerin, oil, and water. 16. The chamber according to claim 1, wherein at least one of said cover member and said base member is formed of a polymer material. 17. The chamber according to claim 3, wherein the other of said base member and said cover member is at least partially formed of a material having a mass density sufficient to produce a transmission loss of greater than about 10 dB. 18. The chamber according to claim 1, further comprising a foam member disposed between the compressor and at least one of said base member and said cover member. 19. The chamber according to claim 18, wherein said foam member is separated from the compressor.
