The present invention relates to an indoor partition wall that is suitable as an indoor partition in a hotel, an apartment house, an office, etc. and that can maintain a high level of sound insulation and sound absorption.
従来の技術 従来から、ホテル、集合住宅など一つの室内を仕切るた
めに用いる間仕切壁では、表面材が、例えば、石こうボ

ても、室内には必ずしも良好な環境が得られない。2. Description of the Related Art Conventionally, in a partition wall used to partition one room such as a hotel or an apartment house, the surface material is made of, for example, gypsum board or lightweight concrete. However, since these materials are sound insulation materials with extremely poor sound absorption performance, in a room partitioned by partition walls, the effect of the reflected sound of the walls is large, and even if some sound insulation effect is obtained, it is not always good in the room. Environment is not available.
このところから、間仕切壁の表面に新たに吸音施工が行
なわれたものも提案されている。しかし、この構造の間
仕切壁は、吸音施工という工数が附加され、施工に手間
がかかるほか、構造が複雑になる。From this point, there is also proposed a new sound absorbing construction on the surface of the partition wall. However, the partition wall of this structure has additional man-hours for sound absorbing construction, which makes the construction complicated and makes the structure complicated.
すなわち、従来例の間仕切壁は次の通りの遮音構造をと
っている。その基本形は第４図（Ａ）、（Ｂ）、（Ｃ）
に示すＡ、Ｂ、Ｃのタイプである。That is, the conventional partition wall has the following sound insulation structure. The basic form is Fig. 4 (A), (B), (C)
The types A, B, and C shown in FIG.
第４図（Ａ）のタイプは、石こうボードや鋼板などの遮
音材１からなるもので、この遮音材１のみによって遮音
する構造である。The type of FIG. 4 (A) is composed of a sound insulating material 1 such as a gypsum board or a steel plate, and has a structure in which the sound insulating material 1 alone is used for sound insulation.
この構造では、遮音作用は遮音材１の材質や重量によっ

く谷形の低下を生ずる。In this structure, the sound insulation effect has a different level of transmission loss (volume insulation) depending on the material and weight of the sound insulation material 1, but as shown in FIG. 5, the valley shape is reduced due to the coincidence effect in the high frequency region.
第４図（Ｂ）のタイプは、２つの遮音材１が間隔をおい

ところの問題がある。The structure shown in FIGS. 4 (C) and (B) is the fifth one.
As shown in the figure, compared with the type shown in FIG. 4 (A), the transmission loss level is high in a high frequency region where there are many noise frequency components, and the valley shape is less likely to decrease due to the coincidence effect. However, there is a problem in this place because the sound reflected from the wall is loud.

(S 2 ) reverses in room B and permeates through the porous metal sound absorbing plate 4 again. Above all, sound is transmitted through the porous metal sound absorbing plate 4, the surface of the sound insulation material 1, and the intermediate portion 7 therebetween. , The reflection is repeated, the sound is reduced in the room B, and the sound pressure level becomes the transmitted sound (S 2 ). Also,
The sound that does not permeate into the room B is similarly absorbed in the room A by repeating the permeation of the porous metal sound absorbing plate 4 and the reflection by the sound insulation material 1.
