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. |
