    Abstract: 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.

    Abstract: To reduce sound emission and at the same time improve stability, a multilayer board for acoustic insulation is proposed that includes, but is not limited to a core sheet arranged between a first and a second covering layer. At least one of the two covering layers is of a closed design. The core sheet is firmly connected in a planar fashion to the covering layers. The core sheet comprises slits that extend within the core sheet in the direction of the core sheet thickness, which slits reduce the shear stiffness of the board and thus ensure an improved acoustic insulation effect. On both sides the core sheet comprises continuous edge zones, which extend parallel to the covering layers. An aircraft can have an interior lining formed by panels that comprise the multilayer boards in order to provide acoustic insulation.

    Abstract: A building material configured to enhance sound attenuation and reduction in dB across a walled partition, the building material comprising a facing membrane, a core matrix disposed about the facing membrane, the core matrix comprising a plurality of microparticles and a binder solution configured to support the microparticles, the building material comprising at least a substantially exposed face, wherein a side of the core matrix is at least partially exposed to increase sound attenuation by reducing reflections from sound waves impinging on the building material as compared to a control building material lacking an exposed face. Two building materials may be used in conjunction with one another about a building structure, such as a stud wall, to create and define a sound trap that functions to reduce sound transmission across the partition formed by the stud wall and building materials.

    Abstract: This invention describes two products both with a plain, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finish painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint. This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent. The inventions also include the paint coating alone or the paint/scrim coating alone.
