Abstract: A sound-absorbing article (e.g., a tufted sound-absorbing article) can comprise a backing having a thickness and a plurality of face fibers associated with the backing. Optionally, the face fibers can comprise a plurality of tufts extending through the backing. The backing can define a plurality of perforations that fully extend through the thickness of the backing and are provided in a pattern to determine an acoustic property of the sound-absorbing article. Within at least a portion of the backing, sequential perforations within the pattern of the plurality of perforations can be spaced center-to-center by between 5 mm and 100 mm.
