Patent number: 7987645Abstract: A noise-reducing substrate for use in a flooring system which ha a subfloor and a floating floor upper layer. The substrate comprises a series of edge butted panels, each having a bottom surface, a top surface and side surfaces. A profile in the bottom surface of the substrate changes the substrate's effective stiffness improving the noise isolation of the substrate compared to the stiffness and noise isolation of the panel without the profile. Additionally, the profile reduces the weight of the panel, thereby reducing manufacturing and installation costs. Material hardness and profile flatness of the upper surface provide the strength and texture required to allow for installation of the floating floor layer without the need for an additional rigid backing material. Such a system greatly improves the impact noise reduction on floor/ceiling systems while keeping the installation cost low and adding little to the total system thickness.Type: GrantFiled: March 29, 2007Date of Patent: August 2, 2011Assignee: Serious Materials, Inc.Inventor: Brandon Tinianov

It is equally effective on new or on existing partitions and can be made to fit all the major brands in the movable partition market. It is attractive, lightweight, durable, inexpensive to manufacture and easy to install. The device is able to absorb incident sound and redirect diffracted sound to a path that will reduce sound levels reaching a listener in adjacent cubicles.Type: GrantFiled: February 28, 2007Date of Patent: August 18, 2009Inventor: Charles H. Stark

Patent number: 7571790Abstract: A sound absorption block installed at a music box, a gymnasium, a studio, etc. to prevent sounds from being heard outside, and a method of constructing the same are disclosed. The present invention provides a sound absorption block, including a lower plate where a plurality of unit structures are regularly arranged in horizontal and vertical directions, the unit structure having rectangular an opening that becomes gradually smaller; and an upper plate arranged on the lower plate to divide each of the openings of the unit structures in four parts. Accordingly, the sound absorption block of the present invention may be made of metals, as well as inexpensive building residues, etc. because a sound wave was decreased and offset regardless of the materials.Type: GrantFiled: June 30, 2005Date of Patent: August 11, 2009Inventor: Bae-Young Kim

Patent number: 7568553Abstract: A noise barrier system composed of a base and a transparent superstructure. A support holds at least two adjacent transparent noise barrier elements and includes a point-fastening of the transparent noise barrier element. A position of upper holding points of the transparent superstructure is arranged at a height of from 70 to 90% of a total height of the transparent noise barrier element and at a distance of from 3 to 50 times a thickness of the transparent noise barrier element from a vertical edge. An upper side of the transparent noise barrier element has a flexure, an angle of the flexure being from 30° to 90° from vertical, and a width of an angled region being from 5 cm to 50 cm, and an entire length of a lower side of the sheet is secured within a groove-shaped depression.Type: GrantFiled: October 9, 2003Date of Patent: August 4, 2009Assignee: Roehm GmbH & Co. KGInventors: Wolffgang Wiebel, Klaus Lublow, Klaus Oberlaender, Norbert Brand, Reiner Lingelbach, Peter Seelmann

Patent number: 7546900Abstract: A panel assembly for a traffic noise barrier wall of the type including opposing slots formed in pairs of vertically-mounted posts is described. The panel assembly includes a sheet, which may be transparent, and a frame disposed along at least a portion of the perimeter of the sheet. Side portions of the frame capture at least a portion of the side edges of the sheet and are received within the opposing slots in drop-down fashion.Type: GrantFiled: February 12, 2004Date of Patent: June 16, 2009Assignee: Evonik Cyro LLCInventors: Eric C. Humphries, Stephen D. Barratt, Ray Stauffer, Paul D. Nowicki, John H. Miller

Patent number: RE41945Abstract: A substrate for use in a flooring system which has a subfloor and a decorative upper layer. The substrate is made in a continuous sheet which has a bottom surface, a top surface, side surfaces and end surfaces. The top surface and the oppositely facing bottom surface are essentially parallel to each other and are spaced apart by the thickness of the substrate. Voids are provided in the substrate, the voids are provided between particles of rubber or other similar material. When the substrate is positioned between the subfloor and the decorative top layer, the particles of rubber provide the strength required to prevent deformation of the substrate in the direction of the thickness and the voids contribute to the sound dampening characteristics required to provide decibel reduction across the thickness of the substrate.Type: GrantFiled: July 25, 2007Date of Patent: November 23, 2010Assignee: Ecore International Inc.Inventor: Paul Charles Downey
