초록 ▼

An enhanced, lightweight acoustic absorber is provided. The acoustic absorber is bounded by the at least one scrim layer without need for additional layers, such as melt-blown or nonwoven layers. The at least one scrim layer includes at least one non-planar, folded scrim layer bonded to itself or another scrim layer to form a plurality of air spaces between folded portions of the at least one scrim layer. The at least one scrim layer establishes a thickness of the acoustic absorber extending across opposite exposed sides of the acoustic absorber.

대표청구항 ▼

1. An enhanced, lightweight acoustic absorber, comprising: at least one scrim layer, said at least one scrim layer including at least one non-planar, folded scrim layer bonded to itself to form a plurality of air spaces between folded portions of said at least one scrim layer. 2. The enhanced, lightweight acoustic absorber of claim 1 wherein said acoustic absorber includes only one of said at least one scrim layer. 3. The enhanced, lightweight acoustic absorber of claim 2 further including a lofty, fibrous material disposed in at least some of said air spaces. 4. The enhanced, lightweight acoustic absorber of claim 2 wherein said scrim layer extends over a serpentine path. 5. The enhanced, lightweight acoustic absorber of claim 2 wherein said air spaces are staggered in overlapping relation with one another. 6. The enhanced, lightweight acoustic absorber of claim 1 further including a plurality of said at least one scrim layer bonded to one another. 7. The enhanced, lightweight acoustic absorber of claim 6 wherein air spaces are formed between adjacent ones of said scrim layers. 8. The enhanced, lightweight acoustic absorber of claim 7 further including a lofty, fibrous material disposed in at least some of said air spaces with at least some of said air spaces remaining void. 9. The enhanced, lightweight acoustic absorber of claim 6 wherein at least one of said scrim layers is planar. 10. The enhanced, lightweight acoustic absorber of claim 6 wherein said at least one non-planar, folded scrim layer extends along a serpentine path. 11. The enhanced, lightweight acoustic absorber of claim 6 wherein said plurality of scrim layers includes a pair of scrim layers bonded to one another. 12. The enhanced, lightweight acoustic absorber of claim 11 wherein one of said scrim layers is planar. 13. A method of constructing an enhanced, lightweight acoustic absorber, comprising: folding at least one scrim layer; andbonding the at least one scrim layer to itself to form a plurality of air spaces between folded portions of the at least one scrim layer. 14. The method of claim 13 further including using a single scrim layer to construct the acoustic absorber without inclusion of additional layers of material. 15. The method of claim 14 further including disposing a lofty, fibrous material in at least some of the air spaces. 16. The method of claim 14 further including forming the air spaces in staggered, overlapping relation with one another. 17. The method of claim 13 further including bonding a plurality of the scrim layers to one another without inclusion of additional layers of material. 18. The method of claim 17 further including disposing a lofty, fibrous material in at least some of the air spaces while leaving at some of the air spaces void of material.
