1. A laminated structure, comprising: a first external layer and a second external layer;at least one internal layer disposed between the first external layer and the second external layer;a first adhesive layer disposed between the first external layer and the internal layer, wherein the first adhe
1. A laminated structure, comprising: a first external layer and a second external layer;at least one internal layer disposed between the first external layer and the second external layer;a first adhesive layer disposed between the first external layer and the internal layer, wherein the first adhesive layer is patterned to cover only a first portion of the internal layer; anda second adhesive layer disposed between the second external layer and the internal layer, wherein the second adhesive layer is patterned to cover only a second portion of the internal layer on a side opposite the first adhesive layer, and wherein all of the first adhesive layer is misaligned with all of the second adhesive layer such that no portion of the second adhesive layer is between the misaligned portion of the first adhesive layer and the second external layer with respect to an axis perpendicular to the internal layer. 2. The laminated structure of claim 1, wherein the structure has a sound transmission class rating of about 30 to about 65 when tested in accordance with ASTM E90-04 and E413-04. 3. The laminated structure of claim 1, wherein the structure has a sound transmission class rating of about 37 to about 41 when tested in accordance with ASTM E90-04 and E413-04. 4. The laminated structure of claim 1, wherein at least one of the first adhesive layer and the second adhesive layer comprises a hot melt adhesive, a solvent based adhesive, a water based adhesive, a UV cured adhesive, or a combination comprising at least one of the foregoing. 5. The laminated structure of claim 1, wherein the first adhesive layer and the second adhesive layer comprise a viscoelastic hot melt adhesive. 6. The laminated structure of claim 5, wherein the viscoelastic hot melt adhesive comprises a temperature sensitive catalyst configured to trigger a crosslinking reaction at a temperature greater than a normal operating temperature but below a disintegration temperature of the hot-melt adhesive. 7. The laminated structure of claim 5, wherein the viscoelastic hot melt adhesive comprises a temperature sensitive catalyst configured to cure the viscoelastic hot melt adhesive in the event of a fire. 8. The laminated structure of claim 5, wherein the viscoelastic hot melt adhesive comprises a temperature sensitive inhibitor, wherein the temperature sensitive inhibitor is configured to trigger a crosslinking reaction in the adhesive when exposed to heat from a fire. 9. The laminated structure of claim 5, wherein the viscoelastic hot melt adhesive comprises an intumescent agent, and wherein the intumescent agent comprises an oxygen-depleting foaming gas. 10. The laminated structure of claim 1, wherein the first adhesive layer and the second adhesive layer comprise a discontinuous pattern of adhesive, wherein the pattern comprises vertical strips of adhesive, horizontal strips, dots, squares, rectangles, polygons, irregular shapes, or combinations comprising at least one of the foregoing patterns. 11. The laminated structure of claim 10, wherein the first adhesive layer and the second adhesive layer comprise a discontinuous pattern of parallel strips of adhesive disposed perpendicular to a longest dimension of the laminated structure. 12. The laminated structure of claim 11, wherein the parallel strips are spaced about 1 to about 4 inches apart. 13. The laminated structure of claim 12, wherein the parallel strips are spaced about 2 inches apart. 14. A laminated structure, comprising: an internal layer disposed between a first external layer and a second external layer;a first adhesive layer disposed between the first external layer and a first side of the internal layer, wherein the first adhesive layer is patterned to provide a covered portion of the first side and an uncovered portion of the first side; anda second adhesive layer disposed between the second external layer and a second side of the internal layer, wherein the second adhesive layer is patterned to provide a covered portion of the second side and an uncovered portion of the second side,wherein the first adhesive layer and the second adhesive layer each comprise a viscoelastic hot melt adhesive, andwherein the covered portion of the first side is misaligned with the covered portion of the second side such that none of the covered portion of the second side is between the covered portion of the first side and the second external layer with respect to an axis perpendicular to the internal layer. 15. The structure of claim 14, wherein each of the first external layer and the second external layer comprise a gypsum fiberboard, and wherein the internal layer comprises a gypsum panel board.
