A method of forming a box-like acoustical substrate is provided. Portions of an acoustical substrate having a decorative surface are compressed to form a flange, a first compressed region, a second compressed region, and a third compressed region. First, second, central, and third uncompressed regions are positioned respectively adjacent to the compressed regions. A left first surface and a right first surface of the acoustical substrate may be folded toward the back surface of the substrate until the second compressed region and the third compressed regions are flush with the central uncompressed region. An outer portion of the left surface may then be folded towards the back surface until the flange is flush with the right edge. The acoustical product may be used as an acoustical trap or duct. When the acoustical product is utilized as a duct, an air impermeable sheet may be positioned on the external surface.

Having thus described the invention, what is claimed is: 1. A method of forming a box-like acoustical product comprising: scoring an acoustical substrate along a plurality of score lines to form a plurality of compression regions, said acoustical substrate having a major side and a back side opposi
Having thus described the invention, what is claimed is: 1. A method of forming a box-like acoustical product comprising: scoring an acoustical substrate along a plurality of score lines to form a plurality of compression regions, said acoustical substrate having a major side and a back side opposing said major side; compressing said compression regions to form first, second, and third compressed regions having four uncompressed regions adjacent thereto, said uncompressed regions including a first uncompressed region, a second uncompressed region, a central uncompressed region, and a fourth uncompressed region, said central uncompressed region being located between said second and fourth uncompressed regions, wherein said first, second, and third compressed regions have densities that are greater than densities of said first, second, central and fourth uncompressed regions; rotating said first and second uncompressed regions toward said back side of said acoustical substrate to locate said second compressed region against said central uncompressed region; rotating said fourth uncompressed region toward said back side of said acoustical substrate to locate said third compressed region against said central uncompressed region; and rotating said first uncompressed region toward said back side of said acoustical substrate to locate said first compressed region against said second uncompressed region and forming said box-like acoustical product. 2. The method of claim 1, wherein said acoustical product is formed with a central void therein defined by said first, second, central and fourth uncompressed regions. 3. The method of claim 1, wherein said compressing step forms a flange adjacent said first uncompressed region, said flange being flush with said fourth uncompressed region after said step of rotating said first uncompressed region. 4. The method of claim 1, further comprising the step of: removing a portion of each of said compressed regions to define fold points to facilitate rotation of said uncompressed regions toward said back side of said acoustical substrate. 5. The method of claim 4, wherein said removed portions are V-shaped notches which collapse during the corresponding said rotating step. 6. The method of claim 1, wherein each said rotating step undertakes an angular displacement of approximately ninety degrees. 7. The method of claim 1, further comprising the step of: positioning an air impermeable layer on said major side of said acoustical substrate. 8. The method of claim 7, further comprising the step of: placing a decorative surface on said impermeable layer to give said box-like acoustical product an aesthetically pleasing surface. 9. The method of claim 7, wherein said box-like acoustical product is a member selected from the group consisting of an acoustical trap, a duct, a duct liner and a duct cover. 10. The method of claim 1, wherein said major side has a decorative surface, and wherein said rotating steps place said decorative surface on each side of said acoustical product. 11. A method of forming an acoustical product comprising: compressing selected regions from an acoustic substrate to form a plurality of compressed regions and uncompressed regions, said plurality of compressed regions having densities greater than densities of said uncompressed regions; moving a first portion of said substrate at a first said compressed region through an angular displacement to move a first uncompressed region; rotating a second portion of said substrate at a second said compressed region to rotate a second uncompressed region such that a central uncompressed region is positioned between said first and second compressed regions, said second portion being rotated through an angular displacement in a direction opposite from said moving step; pivoting a sub-portion of said first portion relative to the remaining part of said first portion at a third said compressed region through an angular displacement to locate a third uncompressed region relative to said first uncompressed region; and repeating said pivoting step, if said pivoting step does not form an enclosed structure, until a last pivoted uncompressed region is positioned adjacent said second uncompressed region to form an enclosed said acoustical product. 12. The method of claim 11, wherein said pivoting step places said third uncompressed region against said second uncompressed region to form an enclosed box-like acoustical product. 13. The method of claim 12, further comprising the step of: forming an interior void within said box-like acoustical product, said void being surrounded by said uncompressed regions. 14. The method of claim 13, further comprising the step of: applying an air impermeable layer to a major side of said acoustic substrate. 15. The method of claim 12, further comprising the step of: placing a plurality of score lines into a back side of said acoustic substrate to define said selected regions between said score lines. 16. The method of claim 15, wherein said compressing step forms a flange adjacent said first uncompressed region, said flange being flush with said third uncompressed region after said pivoting step.
