【発明が解決しようとする課題】然しながら、従来技術
には、下記〜の問題点がある。 室内外間の遮音についての考慮はあるが、室内音場で
の音の拡散、フラッターエコーの防止についての考慮が
ない。However, the prior art has the following problems. There is consideration for sound insulation between indoors and outdoors, but there is no consideration for sound diffusion in the room sound field and prevention of flutter echo.

は、音の拡散によって回避できる。また、室内音場で
は、平行壁間での音の反射による音の往来が不快な反響
（フラッターエコー）を生ずる。That is, in the room sound field, the loudness of sound is apt to be biased for each frequency, and this becomes muffled sound. This muffled sound can be avoided by sound diffusion. Further, in the room sound field, the traffic flow due to the reflection of the sound between the parallel walls causes an unpleasant echo (flutter echo).

昼間等に望まれる低遮音状態、夜間等に望まれる高遮音
状態の如くに遮音性能を多様化できない。With respect to the sound insulation performance between the indoors and outdoors, the sound insulation curtain and the sound insulation panel are opened and closed to simply form two states, that is, a state without sound insulation and a state with sound insulation. For this reason,
The sound insulation performance cannot be diversified such as a low sound insulation state desired in the daytime and a high sound insulation state desired in the nighttime.
【０００６】開閉戸や防音パネルは、窓開口部を開い
たとき、窓開口部の側傍に設けた収納部に収納する必要
があり、窓開口部が設けられる壁に上記収納部を設ける
に足る面積を必要とする。When the window opening is opened, it is necessary to store the door and the soundproof panel in a storage provided on the side of the window opening. To provide the storage on the wall where the window opening is provided. It needs enough area.

することを目的とする。It is an object of the present invention to achieve sound insulation between indoors and outdoors, and to prevent sound diffusion and flutter echo in an indoor sound field irrespective of the wall structure provided with window openings. Another object of the present invention is to diversify the sound insulation performance between indoors and outdoors.

ターエコーを防止する（図８（Ｂ））。(2) When high sound insulation performance such as daytime is not required, the window opening 31 is closed only by the sound insulation board 33,
A low sound insulation performance is secured between indoors and outdoors (Fig. 8 (B)). At this time, the surface of the sound insulation board 34, which is held on the ceiling side, facing the interior space is inclined as an acoustic reflection surface 34A with respect to the interior wall surface, diffuses the sound in the room and avoids the muffled sound, and Flutter echo between the interior wall facing this and the interior wall is prevented (FIG. 8 (B)).

両側が壁面だけであるため開放感も大きい。At this time, the sound insulation boards 33 and 34 are opened by rotating above the window opening 31 and are not housed like the housing provided near the side of the window opening 31. Therefore, it is not necessary to provide a storage portion on the wall on which the window opening 31 is provided,
Irrespective of the area of the wall, since both sides of the opened window opening 31 are only wall surfaces, a feeling of openness is great.

(5) By providing an elastic sealing material 38 having an endless winding shape at a portion where the window opening 31 and the sound insulation board 33 are in contact with each other, the sound insulation board 33 is improved in airtightness and has a cushioning property when closing the sound insulation board 33. Can be improved.

Only the board 41 is provided. Sound insulation board 41
Has a convex acoustic reflection surface 42 on the surface facing the indoor space with the window opening 31 closed. The sound insulation board 41 of FIG. 11 is an example in which the sound reflection surface 42 of one mountain is provided, but the sound reflection board 42 of two mountains may be provided.

That is, when the window opening 31 is closed by both the sound insulation boards 33 and 41, the surface of the sound insulation board 41 facing the indoor space becomes the convex acoustic reflection surface 42, which diffuses the sound in the room and avoids the muffled sound, and Flutter echo between the sound insulation board 41 and the interior wall facing it is prevented (FIG. 10 (A)).
