Conventionally, various sound-absorbing materials have been used as interior materials to reduce reverberation in rooms that require high acoustic performance, such as audio rooms and studios, but it is not possible to use sound-absorbing materials for all interior wall and ceiling materials. In addition, the surfaces of furniture, audio equipment, etc. should be made of metals, plastics, or other materials with low sound absorption properties.
A combination of materials such as glass is used.
従つて、家具や機器の表面で反響が大きくな
り、部屋全体としての残響時間が長くなつて音響
的な歪みが生じ易いという欠点があつた。 Therefore, there is a drawback that the reverberations on the surfaces of furniture and equipment become large, the reverberation time of the entire room becomes longer, and acoustic distortion is more likely to occur.

The sound absorbing plate A according to the present invention is used in various ways as shown in FIGS. 6 to 9.
A part of the sound coming from each direction in the room first passes through the sound absorption holes 3 on the front side and diffuses in the hollow part 1 in the sound absorption plate A, then passes through the sound absorption holes 4 on the back side and is diffused in the porous sound absorption material 5. However, since the positions of the front and back sound absorbing holes 3 and 4 are shifted from each other, the porous sound absorbing material 5 on the back side is not visible from the outside, which is not only desirable in terms of appearance, but also because the back side sound absorbing holes 4 It is also possible to increase the size and improve sound absorption performance.
更に、板材２内部に一方向に連続する中空部１

効果向上に貢献する。 Furthermore, a hollow portion 1 that continues in one direction inside the plate material 2 is provided.
, the sound that enters through the front side sound absorption hole 3 is diffused in this hollow part 1, so two-stage sound absorption is possible, and sound absorption in the low frequency range is also improved due to lateral diffusion. The sound-absorbing holes and the porous sound-absorbing material on the back side absorb low-frequency sounds that are diffused laterally and do not appear on the front side, contributing to improved acoustic effects.
以下、本考案に係る化粧吸音板A1を図示実施

２の裏面に多孔質吸音材５が配設されている。 FIG. 1 shows a first embodiment of a decorative sound absorbing board A according to the present invention, in which one or more hollow parts 3 are arranged in a board 2 (in the illustrated embodiment, a plurality of elongated hollow parts 1 continuous in one direction are arranged in parallel). (However, it is of course not limited to this.)
A front side sound absorption hole 3 and a back side sound absorption hole 4 which are formed and communicate with this hollow portion 1 are provided on both the front and back sides of the plate material 2 with their positions shifted from each other. is installed.
板材２は、ケイカル板、合板等が用いられる

When the grooves 7 are formed on the surface of the plate material and the sound absorption holes 3 are opened on the surface side, the sound absorption properties are further improved due to the unevenness of the surface, and the surface design has a three-dimensional appearance, making it a highly cosmetic sound absorber. be able to. In the case of FIG. 2, the back surface of the porous sound absorbing material 5 is lined with plywood or other ordinary back board 8, and
This is an example of a single-sided decorative sound absorber A1 by fitting a frame material 9 around it, and since it is reinforced by the frame material 9 and a back plate, it is easy to attach to a wall surface or the like.

ものである。 Next, the manner of use of the decorative sound absorbing body A according to the present invention will be explained with reference to FIGS. 8 to 11. FIG. 8 shows an example in which a notch 10 for fitting is formed in a double-sided sound absorber A 2 and combined in a cross shape, and the sound absorber A 2 is used by hanging from the ceiling or standing on the floor. FIG. 9 shows one-sided or double-sided sound absorbers A 1 and A 2 erected on a base plate 11.
Use it like a screen. Figure 10 shows an example in which the single-sided sound absorber A 1 is used as a component of the ceiling surface and is also placed diagonally at the corner of the ceiling, which prevents reflections on the ceiling surface and the corners of the ceiling. be.

果を得る事が出来る。 FIG. 11 shows an example in which a single-sided sound absorber A1 is curved to have an arcuate cross-section, and is used by being placed at a corner of a wall or a corner between a wall and a ceiling. In the example shown in the figure, the side of the plate 2 with the sound absorption holes 3 and 4 formed therein is curved in a convex shape, but the invention is not limited to this, and the side of the plate 2 may be curved so as to have a concave surface. However, it goes without saying that it can also be curved into a convex or concave spherical shape. Such a curved surface may be formed using a curved plate 2 in advance, or a bending groove may be provided in the plate 2 and the plate may be bent and attached during construction. Therefore, the decorative sound absorbing material A of the present invention can be used in rooms that require high acoustic effects such as audio rooms and studios according to the various usage modes described above.
A part of the sound coming from each direction of the room first enters the front side sound absorption hole 3, then diffuses in the hollow part 1, and after that part of the sound is absorbed, the sound that is not absorbed and The remaining sound enters the back side sound absorption holes 4 and is finally absorbed by the porous sound absorption material 5. As a result, the reverberant sound in the room is significantly reduced and a high acoustic effect can be obtained.

As described above, the present invention provides a sound absorption hole reaching the hollow part on the front side of a plate material having a hollow part continuous in one direction, and a sound absorption hole reaching the hollow part on the back side of the plate material at a position away from the front side sound absorption hole. Since the sound absorption holes on the back side are provided and the porous sound absorption material is placed on the back side of the board, as mentioned above, some of the sound coming from each direction of the room first enters the sound absorption holes on the front side, and then After the sound is diffused in the hollow part and part of it is absorbed, the remaining sound that was not absorbed enters the sound absorption holes on the back side and is finally absorbed by the porous sound absorbing material. Since the space between the front and back sides has a double structure with sound absorption holes on the front and back sides, and the sound absorption holes are staggered from each other, sound can be absorbed in two stages: the hollow part, the bent part of the sound absorption hole, and the hollow part. Not only can this improve sound absorption, but when the sound is diffused from the sound absorption holes on the surface side to the hollow part that continues in one direction, the sound in the low frequency range with a long wavelength is also absorbed. It has the advantage of being able to achieve acoustic effects, and in particular, low-frequency sounds that are laterally diffused by the sound-absorbing holes on the back side and the porous sound-absorbing material on the back side are absorbed and do not appear on the front side. Second
By providing a hollow part inside the sound absorbing board, it has the advantage of being lighter and easier to hang from the ceiling, making it easier to handle.
Thirdly, since the front and back side sound absorption holes are open and offset from each other, the porous sound absorption material on the back side cannot be seen from the front side sound absorption holes, which has the advantage of a good appearance, and at the same time, the back side sound absorption holes are not visible. This has the advantage that the sound absorption holes on the back side can be made larger and the area of the holes on the back side can be increased to improve sound absorption.
