摘要:
The present patent concerns the construction of various types of paneling for the ships internal areas lining with layers of fire-resistant and sound-isolating materials, that hold in with multiple layers of Magnesium content. These non flammable isolating panels, when appropriately bound together, form a final complex construction, which is also non flammable, with strict specifications of sound-isolation, high strength in extreme strains and low weight. The following special characteristics constitute the originality of the patent: a) Chemical composition (components specific percentages / Absence of Sulfur Magnesia) and production mode of the binding material. b) Internal structure, connection and reinforcement of the paneling layers. c) Assembling methodology of these panels for the prefabrication, transportation and installation of various sections of the accommodation areas, so that, after their installation and modulation on the ships, they: 1) Meet the strict specifications of sound-isolation. 2) Meet the strict specifications of fire-resistance. 3) The strength of these materials as well as the strength of the formed areas, during the extreme strains of the ships in the sea under the most sever conditions, are ensured. 4) The weight reduction, in comparison with the conventional panels, is ensured.

Acoustical diffuser apparatus for supporting and enhancing the performance of speakers (110, 214, 1020). A preferred apparatus includes a diffuser panel (10, 40, 60, 70, 540, 730, 1010, 1012) that has an outwardly facing non-planar diffuser surface and an opening corresponding to each speaker (110, 214, 1020) for receiving at least a portion of the corresponding speaker (110, 214, 1020) therein. The diffuser panel (10, 40, 60, 70, 540, 730, 1010, 1012) does not cover the sound emitting surface of at least one speaker (110, 214, 1020). The diffuser panel (10, 40, 60, 70, 540, 730, 1010, 1012) may have acoustically transparent material (42, 44, 158, 546) affixed thereto. Methods for installing the diffuser panels (10, 40, 60, 70, 540, 730, 1010, 1012) into existing wall or ceiling structures without compromising the structural integrity of such structures are also disclosed.
摘要:
Die Erfindung betrifft eine Absorbereinheit zum Absorbieren von Schall, insbesondere in geschlossenen Räumen, umfassend mehrere Platten aus Absorptionsmaterial für Schall, wobei wenigstens zwei benachbarte Platten unter Bildung eines dazwischenliegenden Luftraums so beabstandet zueinander angeordnet sind, dass sie für Frequenzen unterhalb von 50 Hz einen Hohlraumresonator bilden
摘要:
Dieses Schallabsorptionselement (1) besteht aus einem von einem Träger (2) gehaltenen Körper aus Schaumstoff (10), vorzugsweise Polyurethanschaumstoff, der mit einer glatten oder mit einer Erhebungen und Vertiefungen aufweisenden Profilaußenfläche versehen ist. Zum Zwecke der Schaffung eines einfachen und wohlfeilen Schallschutzsystemes, das in der Industrie und im Gewerbe universell einsetzbar ist, u.zw. sowohl in Alt- als auch Neubauten, ist der Träger durch ein mit dem Schaumstoffkörper (10) verbundenes und diesen mindestens an Randzonen unterstützendes Gitterwerk gebildet. Bevorzugt besteht dieses Gitterwerk (2) aus Draht.

摘要:
To provide a sound absorbing structure having a superior sound absorbing characteristic and an external appearance of the sound absorbing structure which does not cause flicker or the like, by disposal, for example, in the front of an air chamber, a plurality of ribs 2a are disposed on one surface of the sound absorbing board body 2, and a plurality of through-holes 3 are provided in basal portions 2b between the ribs 2a to form a porous structure. Concealing materials 5 are provided between the ribs 2a of the sound absorbing board body to conceal the through-holes 3, respectively.
