The invention relates to an insulated panel, in particular a wall panel or roof panel, including a foamed core layer and a cover layer affixed to the foamed core layer. The invention also relates to an insulating covering, in particular a wall covering or floor covering, including a plurality said insulated panels.

A floor element includes a substrate made of polymer, a top layer on one of the two sides of the substrate and a polymeric foamed layer on the other of the two sides of the substrate. The density of the polymeric foamed layer is less than 120 kg/m.sup.3.

An impact-absorbing device and a structure for blocking noise between floors by using same are proposed. The impact-absorbing device has a body (100) including an upper cylinder (120), of which the inside is empty and which has an opening opened downward, and a lower container (140), of which the upper end is inserted into the upper cylinder (120), so that the length thereof can extend and contract has an elastic support (160) formed in the transverse direction inside the upper cylinder (120) and/or the lower container (140), and includes a transmitting body (180), which is supported by the elastic support (160) so as to transmit, to the elastic support (160), impact applied to the upper cylinder (120), and thus impact is absorbed since the elastic support (160) is elastically deformed by the transmitting body (180) while the length of the body (100) is reduced due to the impact.

The present invention relates to: a floor tile including a fabric material, and comprising a balancing layer, a noise prevention layer, a functional sheet layer, a fabric material layer, and a surface coating layer; and a manufacturing method thereof and more specifically to a floor tile including a fabric material and a manufacturing method thereof, the floor tile being a functional tile having a natural texture and a three-dimensional effect possessed by the fabric material, having excellent durability, preventing delamination of the fabric material layer, exhibiting excellent mechanical properties such as tensile strength, and enhancing cleaning facilitation.

A system for introducing a noise-dampening polymer in-line in the manufacturing process of a manufactured wood product to achieve higher acoustic performance in siding, sheathing, roofing, flooring, and similar applications using the manufactured wood product. Several lines or bands of the noise-dampening polymer are deposited transversely across one side or face of the product. The polymer is deposited where the product is expected to contact joists or studs. The polymer may be a viscoelastic polymer.

In a sound absorption panel formed by stacking a plate perforated with a hole having a hole size smaller than a fiber length such as expanded metal, a honeycomb material, and felt-like fiber between the perforated plate and the honeycomb material, and joining the perforated plate, the felt-like fiber, and the honeycomb material to each other with an adhesive, the adhesive applied to the perforated plate is permeated into a surface of the felt-like fiber exposed from the hole to fix the fiber on the surface.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.

The present invention discloses an assembly of prefabricated wall modular decoration, comprising a conventional decorative material, a plate, a movable laminating layer and a protective layer. The conventional decorative material being mounted on the surface of the plate, a number of movable laminating layers being evenly spaced between the plate and the protective layer making a sound-insulated air gap between them, and the protective layer being mounted on the surface of the wall. The present invention also discloses an installation method for the assembly above. Due to the traditional decorative material, the plate, the active lamination layer, and the protective layer of the present invention are set to be installed on the wall in turn, together with the sound-insulated air gap within the structure, which is not only simple to manufacture and easy to install, but also has better sound absorption performance which could reduce the noise nuisance.

Provided is technology to reduce interlayer noise occurring in a multi-story house such as an apartment, and more particularly, an environmental and contextual custom-built artificial intelligence (AI) based, interlayer noise abatement apparatus that defines a standard of interlayer noise based on a user environment or a user-specified context, allows an interlayer noise maker to recognize when the noise exceeding the above standard occurs and allows the interlayer noise maker to voluntarily reduce the interlayer noise, and a method of the same.
