  • Patent number: 10538957
    Abstract: A sound proofing window system for use with an acoustic door is disclosed. The system includes 2 fully decoupled acoustic reveal formed between 2 acoustic windows, thereby providing a higher level of sound proofing than is achievable with existing art. A decoupled acoustic reveal means that there is no path of contact between the two acoustic windows that is unbroken by soundproofing material. Further, the acoustic windows may be positioned fully or partially outside the thickness of the door to increase the air gap. Prior art systems may attempt to partially decouple the acoustic reveal. A windowed standard 1.75 inch acoustic door according to the present invention provides an STC rating of 56-57, which is far superior to the 35-47 STC rating comparable prior art. The STC rating of the present invention on a 5 inch thick door is estimated at 64 compared to 54 using conventional technology.

  • Patent number: 9516966
    Abstract: A sound-insulating curtain includes a sound-absorbing core formed by laminating porous sheets and films, is covered by covers, and sewn in an integrated manner. Even after being integrally laminated, adjacently laminated layers are not excessively restrained in places other than sewn areas, and therefore displacement and deformation between layers caused by sound pressure can be tolerated. Sound absorption effects are appropriately produced by each layer, which tolerates such displacement and deformation, while reliably maintaining integrity during handling. Thus, the entire curtain maintains the ability to absorb sounds, efficiently attenuates noise that attempts to pass through the curtain, and suppresses the transmission of noise, thereby enabling noise to be reliably prevented from passing through the curtain.

The partitions are movable along a guide provided in a ceiling. In the room, furniture and a speaker are set. When sound from the speaker is reflected by the furniture and the reflected sound is given to a user, the acoustic effect is lessened. Accordingly, the partitions are moved in front of the furniture. Further, the partitions are moved so as to be symmetrically arranged with respect to the speaker. The movement of the partitions can produce an acoustic space in which the reflected sound is uniform. The present invention is applicable to a partition that enhances the acoustic effect.

  • Patent number: 7712579
    Abstract: It is an object of the present invention to provide a floor silencer that has good transport efficiency due to an ability to be transported in a flat state, and can be assembled to a floor panel of a vehicle by folding along a band-like concave portion. The floor silencer is used with a first surface side in contact with a floor carpet, and a second surface side in contact with the floor panel of the vehicle. The floor silencer also has the band-like concave portion and can be folded along the band-like concave portion. The floor silencer is transported in a flat state and not folded during transport, and is used folded along the band-like concave portion during assembly.

  • Patent number: 7661511
    Abstract: Perforations of a board for building material are formed by a number of recesses (13), or a number of recesses (13) and through-holes (12). A bottom face (16) of the recess forms a face for screwing or driving the fixing element (70) thereto. A color of the bottom face is set to have a brightness of color decreased in comparison with a color of a surface (18) of the board. A substrate of the board is a gypsum board and the bottom face of the recess is formed by a liner paper for gypsum board. According to such a board, a region for screwing or driving the fixing element thereto can be ensured without impairing regularity, uniformity or architectural design of the perforations, and putty finishing or the like for an exposed part of the fixing element can be omitted.

  • Patent number: 7581619
    Abstract: A sound-baffling arrangement for use in conjunction with an air-handling unit. One or more sound baffle columns are mounted for rolling or sliding movement within the interior of the air handling unit housing. Each baffle column may be selectively moved between a use position proximate to the fan assemblies, and a non-use position more distal from the fan assemblies. The movable sound baffles permit the air-handling unit to be fabricated to fit within a smaller housing, and thus to have a smaller, more economical footprint.

  • Patent number: 7571790
    Abstract: 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.

  • Patent number: 7565951
    Abstract: An acoustic assembly including a thin sound absorbing panel supported by foldable mounting brackets is adapted to be mounted upon the walls of an indoor listening enclosure. The space behind the panel functions as an acoustic diffusion chamber which augments the acoustic performance of the panel. A number of such assemblies are employed in a manner such that the panels are offset from the wall and downwardly angled.
