摘要： A movable, prefabricated wall panel having a rigid rectangular frame. A core structure is disposed in the region bounded by the frame, which core structure preferably comprises at least one honeycomb layer. Sheetlike skins are fixedly secured to opposite sides of the frame and extends across the region bounded by the frame for confining the honeycomb layer therebetween. A plurality of small openings are formed in either or both of the skins so that they communicate with cells of the honeycomb layer to create Helmholtz sound-absorbing chambers. Each sheetlike skin is covered by a layer of porous fiberglass material for absorbing sound, which layer includes an inner thin mat of high-density fiberglass which is in turn covered by a relatively thick outer layer of low-density fiberglass. This outer layer has a variable density gradient across the thickness thereof, which density gradient progressively increases across the thickness toward the mat.

摘要： A panel having a cellular core and an acoustically semi-transparent facing is provided. The core, which may be a honeycomb, has cells opening to a face of the core. The facing is bonded to the face of the core such that pillow-like portions of the facing extend into the open cells of the core to provide a mechanical interlock between the facing and the core and to improve the absorption of acoustic energy directed upon the panel. The panel may include a layer bonded to the core opposite the facing for reducing the transmission of acoustic energy through the panel or for increasing its strength and rigidity. Preferably, the facing is non-homogeneous such that the density of the pillow-like portions is less than the portions of the facing adjacent the structure of the core. The panel may be formed by heating and compressing an uncured fibrous element of relatively uniform thickness and density against a cellular core. A heated platen may be used to produce a relatively flat, hardened outer surface of the panel.

摘要： A sound-absorbing building component for indoor paneling consisting of at least two superimposed sheets, preferably made of a synthetic resin. At least one of the sheets is provided with cup-shaped indentations lying side-by-side in the manner of a grid, the bottom surfaces of these indentations being excitable to lossy vibrations upon the incidence of sound. The upper rims of the cup-shaped indentations are all covered by a further planar sheet which is likewise capable of vibrations. This further sheet seals off the air volumes contained in the individual cup-shaped indentations in an airtight fashion. Small lumpy or irregularly-sized bodies can be provided on the bottom surfaces of the cup-shaped indentations.

摘要： Method of making attenuation sandwich panels having a cellular core positioned between and bonded to an imperforate facing sheet on one surface thereof and a perforate sheet with an outer layer of porous fabric material adhered to the other surface. The combined perforate facing sheet and porous fibrous material have a predetermined open surface area prior to its adherence to the cellular core. A coating of adhesive is applied to either the facing sheets or to the facing surface of the cellular core. The sheets are then properly positioned with respect to the cellular core. The porous fabric surface of the combined perforate sheet and porous fibrous material is positioned against a perforated plate. The opposite surface of the perforated plate is positioned against a bonding tool that has a plurality of longitudinal grooves on its perforated plate adjacent surface. This combination is then placed in a press or the like where pressure is applied from the facing sheets towards the core and is then heated until the adhesive is cured.

摘要： A movable, prefabricated wall panel having a rigid rectangular frame. A core structure is disposed within the region bounded by the frame, which core structure comprises at least one honeycomb layer. Sheetlike skins are fixedly secured to opposite sides of the frame and extend across the region bounded by the frame for confining the honeycomb layer therebetween. A plurality of small openings are formed in either or both of the skins so that approximately a single opening will communicate with a single cell as defined by the honeycomb layer. The opening and the cell are of a preselected size so as to function as a sound absorbing chamber. The sheetlike skins are also covered by a layer of fibrous sound absorbing material, preferably fiberglass.

摘要： An acoustical facing sheet comprising a permeable member having perforations therethrough and tubular elements extending therefrom on one side in register with said perforations. The structure provides a lumped acoustic impedance having an acoustic resistance proportional to frequency, and an acoustic inertance that is inversely proportional to frequency. It permits the design of highly efficient laminar-type sound attenuating panel structures having an unusually low first resonant frequency without impairing performance at the higher frequencies, and occupying smaller volume than prior devices.

摘要： A sound absorbing structure, generally comprising a honeycomblike cellular layer, an impermeable backing closing one end of the cells, a permeable facing covering the other end of the cells, and oblique porous or permeable partitions having a specified flow resistance in each cell, for providing controlled acoustic absorption over a wide range of frequencies and having a minimum ability to wick and retain liquids. The operation of the structure is relatively independent of the materials from which it is made, and may for example be fabricated entirely from metal. It is particularly suitable for sound attenuation in jet engines and other adverse environmental conditions requiring sound absorptive panels, baffles, duct liners, and duct splitters.
