Definitions
- This invention relates to a sound-damping wall element having a frame and at least two panels connected to the frame in such a manner that there is produced an inner space that is sealed off from the surroundings and which is bounded on the one hand by the inner surfaces of the panels and on the other hand by an inner circumferential surface of the frame extending from one panel to the other.
- a wall element of this kind is known from Dutch patent application 83.00212, in which the frame is hollow and functions as a resonator body connected through a slit to the space between the two panels.
- This construction is especially suitable for windows whose panels consist of glass panes and whose frame is made e.g. from aluminum or a similar material suitable for a hollow construction.
- this sound-damping construction is also suitable for other types of wall elements, such as fixed panels and doors, in which case, however, the special frame construction may result in complications or may be too expensive.
- a good resonator effect requires a given length of the access opening and/or slit which, like the volume of the resonator space, is tuned to the main frequency to be damped.
- This length can be obtained in a simple manner when according to a further embodiment of the present invention, the element, in panel surface direction, has a width that corresponds with the required length for the access opening of the resonator.
- the element is preferably provided with a plurality of bores serving as access openings for a Helmholtz resonator, since this has an optimum damping efficiency.
- the element consists of at least one slat, e.g. of wood.
- a slit resonator can then be obtained by means of two slats or one slitted slat, or, as stated above, a preferred Helmholtz resonator by providing a plurality of bores in a slat.
- the total inner space of the wall element, minus the portion separated therefrom for forming the resonator, or the remaining inner space, will be many times larger than the resonator space itself, while the diameter of an access opening or the height of an access slit is only a part of the distance between the two panels.
- the portion of the inner space not forming part of the resonator space accommodates further soundproofing arrangements, such as a glasswool blanket and/or a gypsum cardboard and the like, which fill up said space only partly, with the access opening or openings for the resonator terminating in the non-filled remaining inner space.
- further soundproofing arrangements such as a glasswool blanket and/or a gypsum cardboard and the like, which fill up said space only partly, with the access opening or openings for the resonator terminating in the non-filled remaining inner space.
- a sound-damping wall element is a door with a wooden circumferential frame and door panels mounted thereon, it is preferred that the element consists of two wooden slats extending the full height of the door, each forming a resonator together with a vertical portion of the circumferential frame.
- FIG. 1 shows a sound-damping wall element composed of a wooden circumferential frame consisting of four frame portions 1a-d on either side of which there is mounted a panel 2, 3, thereby forming an entirely enclosed inner space 4.
- Panel 2 is partly removed in Fig. 1 to show the interior of the wall element.
- frame portion 1a and slat 5a, and frame portion 1 c and slat 5d, respectively a space separated from the inner space 4 and functioning as a resonator space 6a, 6b.
- Each resonator space is in open communication, through bores 7 in slat 5a, 5b, with the remaining portion of the inner space 4.
- the total bore area of bores 7, as well as the volume of the resonator space 6a, 6b are tuned to the principal frequency to be damped. The latter defines at the same time the required length of bores 7 and thus the width in panel direction of the slat 5a, 5b.
- the remaining portion of the inner space 4 contains further sound-insulating and fire-proofing or fire-retarding means in the form of a gypsum cardboard 8 and a glasswool blanket 9, abutting against panel 3, and panel 2, respectively, so that the portion of the inner space 4 remaining after installation of said means remains in direct contact through bores 7 with the resonator spaces 6a, 6b.
- the resonator spaces 6a, 6b are both tuned to the same frequency by imparting to them the same volume and the same passage area and length of the access opening.
- resonator space 6a can also be tuned to a different frequency than resonator space 6b by changing the above magnitudes relatively thereto.
- resonators that may be tuned to any desired frequency can be installed along the short side of the frame as well. Tuning to a desired frequency is possible by subdividing resonator spaces 6a, 6b into spaces of a given volume; it is likewise possible to shift slat 5a or 5b to the left or to the right.
- slit resonators by providing longitudinal slits in the slats, instead of bores, or by mounting a slat on each panel in such a manner that the desired slit remains therebetween.
- a preferred embodiment concerns the provision of the desired length of access opening by selecting the slat width accordingly.
