されている。Next, the case where the outdoor soundproof board according to the present invention formed as described above is applied to a soundproof wall will be explained. 9 To construct a soundproof wall using the outdoor soundproof board according to the present invention,
As shown in FIG. 7, the outdoor soundproof boards are stacked up to a predetermined height that corresponds to the height of the soundproof wall, with the sides of the plate member 10 butted against each other, and the stacked outdoor soundproof boards are connected to the noise source. Install multiple lines along both sides of railroad tracks, automobile roads, etc. At this time, the outdoor soundproof boards are installed such that the first lid 3 side of the sound deadening means 2 faces the noise source. Then, mutually opposing ends of the plurality of adjacent stacked outdoor soundproof board plate members 1 are supported by both side recesses of the H-shaped steel member 15. This H-shaped steel material 15 is supported by a foundation buried underground.

表面における反射を繰返すことにより干渉及び減衰を起
こして消音される。In the soundproof wall configured in this way, when sound, which is noise, is radiated to the soundproof board constituting the soundproof wall, this sound is transmitted from the first communication hole 6 of the sound damping means 2 to the casing. It is introduced into the space formed by the body. At this time, since the housing is not in a sealed state due to the second communication hole 7 or the communication pipe 10, the sound is smoothly introduced into the interior of the housing. The sound is transmitted to the inner surface of the casing and the first casing. Repeated reflections on the surface of the second sound guide tube 8.9 cause interference and attenuation, and the sound is muffled.

Reflected on one side. This reflected sound interferes with the reflected sound reflected by each other muffling protrusion 12 and is muffled. Furthermore, the sound that is not reflected by the side surfaces of the pentagonal pyramid but propagates into the hollow part 14 through the opening 13 is repeatedly reflected by the inner surface of the hollow part 14, It is introduced into the interior and causes interference and attenuation to muffle the sound.
上述のように本発明に係る屋外用防音板は、放射された
音響を消音する効果があるので、この防音板により構成
される防音壁は、第７図に示すように、防音効果を損な
うことなく、薄く構成することができる。As mentioned above, the outdoor soundproofing board according to the present invention has the effect of muffling radiated sound, so the soundproofing wall made of this soundproofing board does not impair the soundproofing effect, as shown in FIG. Therefore, it can be constructed thinly.
なお、本発明に係る屋外用防音板において、上記消音手

てさらに多数の導音管を設けるようにしてもよい。In the outdoor soundproof board according to the present invention, the casing constituting the sound deadening means 2 is not limited to the cylindrical shape as in the above-mentioned embodiments, but can be changed into various shapes as appropriate. Further, the number of sound guide tubes arranged inside the housing is not limited to two as in the above embodiment, and a larger number of sound guide tubes may be provided as necessary. .
さらに、上記消音突起１２は、上述の実施例のような三
角錐形状に限定されず、四角錐形状等の種々の角錐形状
