Definitions

  • the present invention relates to a damping assembly for reducing vibrations, sound or noise.
  • the damping assembly is suitable for reducing vibrations, sound or noise propagating from one room of a building or accommodation to an adjacent room.
  • Common measures for sound proofing include increasing the thickness of the separating wall or floor/ceiling, adding an additional amount of sound damping material and increasing the number of composing layers of the separating wall or floor/ceiling.
  • Additional measures include the employment of highly specialized damping materials built in or applied to the separating wall or floor/ceiling. However, these solutions are associated with high costs.
  • Resilient fastening elements such as e.g. the resilient fixing arrangement of WO 2008/115119 A1
  • a resilient fastening element generally comprises a spring means for resiliently retaining the different constructions at a distance from each other, thereby as far as possible preventing mechanical contact between the constructions.
  • Improper assembly of such resilient fastening elements with the separate parts and/or in combination with other features of these separate parts may, however, result no or even increased transmission of sound or noise, which is highly undesired. For example, improper assembly may yield an internally resonating wall or floor/ceiling, which is less damping than the corresponding wall or floor/ceiling in which traditional stationary fastening elements have been used.
  • an improved damping assembly e.g. damping wall or floor/ceiling, for reduction of vibrations, sound or noise would be advantageous.
  • a damping assembly for reducing vibration, sound or noise propagation between at least two structures having the features of claim 1 is provided.
  • a damping assembly e.g. a wall or floor/ceiling, which is thinner than a damping wall or floor/ceiling of the prior-art, also allowing for equal or improved sound reduction capability.
  • An idea of the invention is to provide an noise reducing assembly for walls or ceilings, wherein the at least two wall sections are resiliently attached to each other, in a way such that a first volume is created between the two wall sections near the position of the resilient attachment, and a second volume being larger than the first volume is created further away from the position of the resilient attachment.
  • the first and second volumes act as dampeners which allows for noise reduction.
  • a further idea is to allow for a solution of improved noise reduction for an existing wall or ceiling.
  • a damping assembly 10 for reducing vibrations, sound or noise propagation between at least two structures.
  • the damping assembly comprises a first structure 101, such as an inner ceiling construction.
  • the damping assembly comprises at least one studwork structure 102 to which the first structure is to be connected.
  • At least one resilient attachment member 103 is provided for resiliently attaching the first structure 101 to the studwork structure 102.
  • the at least one resilient attachment member 103 When attached to the first structure and the at least one studwork structure the at least one resilient attachment member 103 creates a space between the first structure and the at least one studwork structure, such that the first structure 101 and the at least one studwork structure 102 are contact with each other only via the resilient attachment member(s) 103.
  • a first perpendicular distance L1 from the first structure to the studwork construction defines the space between the two.
  • the at least one studwork structure 102 is connected to a second structure 104, 101 oppositely arranged to that of the first structure 101.
  • the second structure may e.g. be a wall foundation or another inner wall or ceiling.
  • the dimensions of the studwork construction and the placement of the second structure 104, 101 in relation to the studwork structure results in the second structure being at a second perpendicular distance L2 from the first structure 101.
  • the first perpendicular distance L1 and a surface area of the at least one studwork structure 102 facing the first structure 101 form a first volume V1.
  • Fig. 1 is a two dimensional cross sectional view of the first volume V1 has been indicated for improved understanding. In Fig. 1 it actually relates to an area due to the two-dimensional drawing, however it should be appreciated that the volume extends in along the depth of the damping assembly in reality.
  • the second perpendicular distance L2 and a surface area of the second structure 104, 101 facing the first structure 101 form a total volume between the first and second structure. The total volume when subtracted with the first volume V1 and a volume of the studwork structure Vs form a second volume V2.
  • the total volume between the first structure and the second structure is made up by the first volume, the second volume and the volume of the studwork structure.
  • the present inventors have realized that when the second volume is larger than the first volume, the first perpendicular distance or first volume is greater than zero, and when the second perpendicular distance L2 is larger than the first perpendicular distance L1, an improved noise reduction between the first 101 and second structures 104 is noticeable.
  • arranging the assembly in a way that the second volume is larger than the first volume is advantageous.
  • propagating sound waves originating from the left side of the first structure 101 will be absorbed by the first structure 101, as well as by the resilient attachment member 103, whereby the first structure 101 will start oscillating in relation to the second structure 104.
  • ambient atmospheric gas residing between first structure second structure in use will also act as a dampener for the relative oscillation of the first and second structures, thereby reducing sound transport between the first 101 and second structures 104.
  • the mechanical sound transport between the first structure and the second structure is kept to a minimum.
  • the first structure 101 may be a plasterboard, Medium Density Fibreboard (MDF) board, High Density Fibreboard (HDF), Plywood, chipboard, Oriented Strand Board (OSB) or being of any other sheet of material suitable for an inner ceiling or wall.
  • MDF Medium Density Fibreboard
  • HDF High Density Fibreboard
  • OSB Oriented Strand Board
  • the present damping assembly allows for a thin sound damping wall construction.
  • the damping assembly in accordance with the embodiment, shown in Fig. 1 may reduce the sound by 8dB in comparison to a common wall or ceiling in which the first structure is rigidly attached to the studwork construction in such a way that L1 is zero.
  • the sound damping of 8dB was observable in the noise frequency range of 50Hz to 5000Hz.
  • the present invention dampens sound better with only a single first structure resiliently attached to a studwork structure, than a conventional solution in which two first structures are rigidly attached to the studwork structure. Accordingly, not only does the solution of the present invention dampens the sound to a greater extent, it also saves space while significantly reducing the costs in view of the conventional solutions.
  • the studwork structure is normally attached to the floor foundation and ceiling (not shown in the drawings). However, in some cases, e.g. where the second structure 104 constitutes an existing concrete wall, the studwork structure could also be attached to the second structure.
  • the studwork structure normally constitutes the floor studwork foundation of the next level of the property.
  • the resilient attachment member could be be any commonly known resilient attachment member. However, preferably the resilient attachment member is configured to attach the first structure with the studwork structure in a one-directional manner, e.g. by screwing it in through the first structure to the studwork construction.
  • a resilient attachment member mainly comprises three portions.
  • a first portion 301 is provided with an outer thread for rigid connection to the first structure 101.
  • An intermediate resilient portion 302 of the resilient attachment member connects the first portion to a second portion 303 which is provided with further outer thread for rigid connection to the studwork structure.
  • the dimension of the further outer thread is preferably less than the outer thread of the first portion 301, whereby the resilient attachment member may be introduced through a hole in the first structure 101.
  • the intermediate resilient portion 302 acts to keep the first and second portion at a distance from each other in a relaxed or idle state. Hence, the intermediate resilient portion 302 returns to its idle or relaxed state when not influenced by any external longitudinal force or sound pressure wave.
  • the first portion 301 is provided with a first mating unit (not shown in Fig. 1 ), such as a protrusion or recess, which is configured to receive a second mating unit of the second portion in a compressed state, in which the first 301 and second 303 portions are forced together.
  • the first portion and the intermediate resilient member may have a hollow interior shape, through which a mounting tool mating with the second portion 303 may be inserted for screwing the second portion 303 into the second structure 104 independently of the first portion 301.
  • the first portion 301 may be configured with an outer recess for mating with a screw driver, thereby allowing for independent attachment of the first portion 301 to the first structure 101.
  • such a resilient attachment member 103 allows for relative rotation between the first 301 and second 303 portion in the relaxed state by using a mounting tool, or non-relative rotation between the first 301 and second 303 portion in a compressed state when the first portion 301 and second portion 303 are mated together.
  • the resilient attachment member may be configured to attach the two structures involved from one direction.
  • the resilient attachment member(s) in Figs. 1 to 4 , 7a , 7b , 8 , and 10 could be mounted from a left to right direction.
  • the resilient attachment member(s) on the left hand side of the studwork construction could be mounted from a left to right direction and the resilient attachment member(s) at the right hand side of the studwork construction could be mounted from a right to left direction.
  • the resilient attachment member(s) of Figs. 9a , and 9b could be mounted from a right to left direction.
  • the mounting tool may be configured with a first member connectable to the first portion 301 of the resilient attachment member 103 and a second member connectable to the second portion 303 of the resilient attachment member 103, whereby upon rotation of the connected mounting tool the first portion 301 is screwed into the first structure 101 and the second portion 303 is screwed into the studwork structure 102.
  • the resilient attachment member may also have an extended state, in which the first 301 and second 303 portions are positioned at a maximum longitudinal distance away from each other. Accordingly, the second perpendicular distance L2 between the first structure 101 and second structure 104, 101 is larger in the extended state than that in the compressed state.
  • the resilient attachment member 103 is in a state between the extended state and the compressed state when the intermediate resilient portion 302 is in its idle state.
  • the first perpendicular distance L1 should always greater than zero, for each state of the resilient attachment member.
  • the first perpendicular distance L1 between the surface of the first structure facing the studwork structure, and the surface of the studwork structure facing the first structure is preferably always greater than zero to make sure that the only mechanical sound barrier between the first and second surface is through the resilient attachment member.
  • the present inventors have found that an improved sound reduction is achieved when the second perpendicular distance L2 is larger than L1, and that L1 is greater than zero. This implies that even if resilient attachment members are used, in the event that the first perpendicular distance L1 is equal to the second perpendicular distance L2, the sound reduction according to tests performed is relatively poor, compared to if L2 is larger than L1.
  • a damping assembly in which L1 equals L2 is shown in Figs. 2a and 2b .
  • the second perpendicular distance L2 is larger than the first perpendicular distance L1.
  • the second volume is at least partly filled with flexible material structure 201.
  • the flexible material structure 201 may be an insulating material, such as rock wool as depicted in Fig. 4 , insulating balls such as plastic insulating balls as depicted in Fig. 3 , glass wool, polystyrene balls, or any other insulating material.
  • the flexible material structure 201 may also have sound damping properties, such as a sound damping material. Many insulating materials possess sound damping properties, whereby these kinds of materials are preferred.
  • the flexible material structure is preferably porous, allowing for accommodating a volume of atmospheric gas.
  • the second volume V2 may be at least partly incorporated as an atmospheric gas within the flexible material structure, and as an atmospheric gas partly exterior to the flexible material structure, in cases where the flexible material structure only partly fills the space between the first structure and second structure, such as in Fig. 10 .
  • the space between the spherical insulating balls containing an atmospheric gas may form part of V2.
  • the second volume created between the second and first structures may according to some embodiments advantageously be at least partly unobstructed by the flexible material structure, thereby providing at least one unobstructed passage between the second structure and the first structure. This improves the atmospheric gas movement within the second volume, which may allow for improved sound reduction.
  • the flexible material structure contains a number of plastic insulating balls
  • the flexibility of the flexible material structure should be adapted to allow for absorption of sound pressure waves. Accordingly, the flexible material structure does not pertain to a fully rigid structure, such as a plaster board, MDF or the like, through which the sound waves easily mechanically propagate, as this adversely affect the sound reduction capability. Also a rigid material would create additional direct mechanical contact points between the first structure and second structure. Instead, a flexible and shapeable material is preferred. Expressed in other terms it is preferred that the acoustic impedance of the flexible material structure is lower than both that of the first structure and second structure.
  • the flexible material structure preferably has a lower density than that of the first structure 101 and second structure 104, 101.
  • Fig. 5 illustrates a damping assembly 10 according to further embodiment, in which the second structure 104 is also resiliently attached to the studwork structure 102 by means of a number of resilient attachment members 103.
  • the second structure may be identical to the first structure, thereby pertaining to an inner ceiling or wall.
  • a difference in view of Fig. 1 is that the second structure is also resiliently attached to the studwork structure.
  • an additional third volume V3 is created in this embodiment, as a third perpendicular distance L3 and a surface area of the at least one studwork structure 102 facing the second structure 104 form a third volume V3.
  • the third volume V3 and the first volume V1 may be roughly equal.
  • Total volume between the first structure and the second structure is formed by the second perpendicular distance L2 and a surface area of the second structure 104 facing the first structure 101.
  • the total volume subtracted by the first volume V1, the third volume V3 and a volume of the studwork Vs forms the second volume in this embodiment.
  • this additional volume may be taken into consideration when defining the second volume.
  • This embodiment is advantageous for walls when sound proofing is desired from both sides of the wall, e.g. in open-plan office environments, and separating walls in apartments.
  • Fig. 6a illustrates a damping assembly according to an embodiment, similar to that of Fig. 1 , in which a further studwork structure 102 and a further first structure 101 is arranged on the opposite side of the damping assembly of Fig. 1 .
  • the further first structure is arranged at a third perpendicular distance L3 from the further studwork structure, and at a fourth perpendicular distance L4 from a surface of the second structure 104 facing the further first structure 101.
  • both the second perpendicular distance L2 and the fourth perpendicular distance L4 is preferably greater than the first perpendicular distance L1 and the third perpendicular distance, respectively.
  • the fourth perpendicular distance L4 and a surface area of the further first structure 101 facing the second structure 104 form a further total volume between the further first structure and the second structure.
  • the total volume when subtracted by the third volume and a volume of the studwork Vs form a fourth volume V4.
  • the further first structure may be denoted third structure for sake of clarity in the appended claims.
  • the second volume V2 is larger than the first volume V1 and if available the fourth volume V4 is larger than the third volume V3.
  • Fig. 6b illustrates a damping assembly according to an embodiment, wherein two inner ceiling or inner wall structures are connected on either side of a studwork structure, without any foundation structure 104 arranged between the two studwork structures 102.
  • L2 is greater than L1 and L3, respectively, and that each of L1 and L3 is greater than zero in order to obtain the desired sound damping properties.
  • the first L1 or third L3 perpendicular distance is in the range of 0,01 to 20 mm, e.g. 1 to 10, such as 1 to 5 mm, such 3 mm.
  • the second L2 or fourth L4 perpendicular distance is in the range of 25 to 500mm, e.g. 50 to 300, such as 50 to 200mm.
  • Fig. 7a illustrates an embodiment in which a further first structure or sheet of material 601 has been mounted on top of the first structure 101.
  • the further sheet of material may e.g. be an additional plaster board, MDF, HDF or optionally glued onto the first structure 101.
  • Fig. 7b illustrates a damping assembly, according to an embodiment, similar to that of Fig. 7a in which the further first structure is rigidly screwed to the first structure by means of conventional screws 701.
  • the at least one resilient attachment member is attached to the at least one studwork structure straight through the first structure and the further first structure.
  • this embodiment requires a slightly longer resilient attachment member than that required e.g. in view of Fig. 7a .
  • the second structure 104, 101 may be rigidly attached to the studwork structure acting as a foundation of a wall, roof or floor of a building or accommodation, whereas the first structure 101 is resiliently suspended in relation to the second structure 104 via the resilient attachment member 103.
  • An advantageous effect of the present invention is that it is possible to assemble the damping assembly in a one-directional manner, as the resilient attachment members may be screwed into the structures in essentially in the same way as commonly is performed when mounting plasterboards.
  • the only difference is that an adapted mounting tool may be required, in case the resilient attachment member is not adapted to a particular standard.
