Panel systems and related methods of controlling sound transmission are discussed. For example, the panel system may include a sound control component, which may include a foam composite of a polymer and an inorganic filler. The panel system may further include an attachment mechanism, e.g., including at least one fastener, at least one bracket, and/or at least one rail or rail system. The attachment mechanism may be configured to secure the sound control component between a first wall and a second wall, such that the panel system controls sound transmission between the first and second walls.

A sound isolation assembly comprising: one or more backing plates; one or more acoustic isolators; and a backing block. The acoustic isolators may be secured between the backing plates and the backing block when the backing plates are fastened to the backing block. When the backing plates are fastened to the backing block, the backing plates are substantially prevented by the acoustic isolators from being in direct contact with the backing block. The acoustic isolators may be fastened to the studs. The sound isolation assembly, when installed in a wall that is supporting a heavy load, raises the Sound Transmission Class rating of that wall.

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.

A sound insulation structure for a building includes: a floor material; a ceiling material opposed to the floor material in a vertical direction with a space in a building interposed therebetween; a partition wall extending in the vertical direction and partitioning the space into a first space and a second space adjacent to each other in a horizontal direction; and at least one face material out of a floor-side sound insulation face material stuck to a portion of the floor material in a range of a thickness of the partition wall and having a coincidence frequency different from that of the floor material, and a ceiling-side sound insulation face material stuck to a portion of the ceiling material in the range of the thickness of the partition wall and having a coincidence frequency different from that of the ceiling material.

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.

An acoustical treatment assembly includes an absorption panel and a diffusion panel that may be removably mounted to the absorption panel. The absorption panel has a first surface, an opposite second surface and a plurality of edge surfaces. The absorption panel has channels defined in either or both of the second surface and the edge surfaces. Each channel has a seat spaced apart from the first surface and the second surface, in which is disposed a magnet. The diffusion panel has a first surface, a second surface and a plurality of interior openings extend from and through the first surface and the second surface. The diffusion panel is formed of a material having a lower audio absorption than the absorption panel. Additional magnets are mounted on the diffusion panel that cooperate with magnets of the absorption panel to removably retain the diffusion panel adjacent to the absorption panel.

An acoustic panel comprises a mounting element and an acoustic damping element. The mounting element is adapted to be mounted to a wall or another structure of a building, and comprises a plurality of protrusions extending from a front side of the mounting element. The acoustic damping element comprises a rear face with a plurality of openings, and is adapted to be mounted to the mounting element with the plurality of protrusions fitting into the plurality of openings to hold the acoustic damping element in place at the mounting element. An acoustic panel system comprises a plurality of acoustic panels and a plurality of connecting brackets.

An acoustic seal for a sound flanking path between an interior architectural separation and a mullion. A seal body is configured as an elongated rail having a base rail portion and a side rail portion. The base rail portion has sides defining a first seal surface for engaging a first interior side of the mullion, and a second seal surface for engaging an end wall of the architectural separation. The side rail portion has sides defining a third seal surface substantially non-parallel with respect to the first seal surface for engaging a second interior side of the mullion, and a fourth seal surface in substantially coplanar relationship with the second seal surface for engaging the end wall of the architectural separation. The first and third seal surfaces may form an inside seal corner for enveloping an outside corner of the mullion defined by the mullion's first and second interior sides.

A modular acoustic structure includes a number of joined acoustic wall panels and acoustic ceiling tiles positioned atop the joined acoustic wall panels. The joined acoustic wall panels define a doorless aperture in the modular acoustic structure, an internal chamber, and a straight acoustic hallway connecting the doorless aperture and the internal chamber via an internal aperture. The straight acoustic hallway absorbs soundwaves travelling between the doorless aperture and the interior chamber. The acoustic wall and/or ceiling panels may include an acoustic absorptive surface and an acoustic reflective surface. The acoustic properties of the interior chamber and/or the straight acoustic hallway may be altered or tuned by changing which of the surfaces faces an interior of the modular acoustic structure. The size of the interior chamber and/or the modular acoustic structure may be adjustable by adding and/or removing acoustic wall and/or ceiling panels.

A privacy apparatus includes one or more substantially cork panels. Each panel can be configured to provide visual and/or sound privacy for a certain work space. The panel can be supported on a floor via one or more base elements and/or may be reinforced in rigidity and/or strength via one or more supports. Some embodiments of the apparatus can include a first panel and a second panel attached together via one or more supports press fit within openings defined in rear faces of the panels.
