A thermoplastic frame for holding acoustical material has extruded square plastic tubing that is inserted or press-fit onto corner connectors and T-connectors to make an open ended enclosure that houses the acoustic material. Once the frame is assembled, the acoustic material is inserted in the open end of the frame.

A noise reduction apparatus can include a frame and multiple spaced apart panels positioned adjacent to each other. Each of the panels or only one of the spaced apart panel elements may have holes therein to receive acoustic waves for absorbing the waves between the panels. The panels can be attached to a frame or other connection structure so that the arrangement of panels can be hung over a work space or positioned in a work space (e.g. in a wall, formed as a partition or wall, included as part of shelving, etc.). The panels can also be incorporated into a light fixture that may hang from a ceiling or be attached to some other type of support (e.g. a table, a base, etc.). The panels can be composed of glass, wood, or other type of material.

Embodiments disclosed herein describe a suspension system. The suspension system includes a substrate comprising a horizontal portion; a rail disposed on a top face of the horizontal portion of the substrate; one or more attachment points attaching the substrate to the rail; and a variable suspension point slidably attached to the rail, where a window of movement of the variable suspension point is provided along the rail and between the one or more attachment points.

A moveable acoustical panel is disclosed for location on a surface comprising a frame having a lower support supporting an upper horizontal support by a first and a second vertical support. A first and second pair of support leg extends angularly from said first end of said frame with first and second plurality of rolling members secure thereto for enabling said frame to be moved along the surface. A flexible acoustical blocking material for blocking acoustical sound is secured to the supports.

A method is provided for assembling a wall system to an existing frame for a wall, floor or roof, including: attaching a first dense, fiber-reinforced cement panel to the frame, the panel having an interior surface facing the frame, and an exterior surface; applying a layer of acoustic dampening material is applied to the exterior surface; and attaching a second dense, fiber-reinforced cement panel to at least one of the dampening material, the first panel, and the frame. A building panel is provided, including, a first panel of dense, fiber-reinforced cement; an internal layer of acoustic dampening material; and a second panel of dense, fiber-reinforced cement such that the dampening material is sandwiched between the first and second cement panels.

A system for mounting objects, such as acoustic panels to a surface is provided. The system includes a door in a façade panel for accessing a mounting structure adapted to receive a fastener that mounts the panel to the surface. The door can include a tab for identifying and opening the door. Methods for mounting objects with an access door and methods for manufacturing tiles are also provided.

An acoustic damping structural system includes studs, tracks, and acoustic damping members. The studs and tracks include a first wall, a second wall, and a third wall that define a channel. The third wall includes a first portion perpendicular to the first wall, a second portion perpendicular to the first portion, and a third portion perpendicular to the second portion to define a ledge along a length of the third wall. The tracks are coupled to a support, such as floor joists and roof beams, in parallel. Opposite ends of the studs are received in the channels of the tracks, with the acoustic damping members received on and coupled to the ledges of pairs of the studs and pairs of the tracks. The acoustic damping members are planar with the ledges and the studs and tracks, respectively.

A precursor to form an impaling clip, and an impaling clip formed therefrom. The impaling clip is configured for mounting an acoustic panel on a structural component, e.g., a wall stud, of a building. The impaling clip includes a base member from which a pair of prongs project upward perpendicular to the plane of the base member. The base member includes at least one hole for receipt of a fastener, e.g., a screw, to fixedly secure the base member of the clip to the structural component. Each prong includes a leg portion terminating in pointed head and outwardly projecting under-cut barbs configured to pierce through the back surface of the panel to lock the prong within the panel so that it is resistant to removal.

An acoustic mount is described for damping vibrations between a primary structure of a building and a secondary structure of a building and which has a vibration damper interposed in use between the primary and secondary structures. The vibration damper is resiliently compressible in the axial direction and has at least one resiliently compressible damper element which is elongated in the axial direction so that the axial length of the damper element is greater than half of a transverse width thereof. The damper element reduces in cross sectional area in the axial direction; has a convex outer surface in planes containing the axial direction; and possesses non-linear axial deflection or compression characteristics under a range of static loading conditions enabling effective vibration damping or vibration isolation for a substantial range of loadings of the acoustic mount in use. Damper elements have a continuous convexity of outer surface extending to a tip and the continuous convex outer surface in a plane containing the axial direction has a curved shape defined by a quadratic equation, including segments of ellipses, parabolas, hyperbolas.

Embodiments relate to a plastic wall panel, comprising a hollow body having external walls and defining an internal cavity. The external walls include: a first major side wall, a second major side wall opposite the first major side wall, a minor top wall, a minor bottom wall, a first minor end wall and a second minor end wall opposite the first minor end wall. The minor top wall and the minor bottom wall each define mating structure to mate and align with another adjacent panel so that multiple panels can be tiled together to form at least part of a sound attenuation barrier. The hollow body defines a passage extending between the first and second major side walls and through the first and second minor end walls to receive a reinforcing beam.
