ることもある。2. Description of the Related Art Conventionally, as a measure for preventing noise generated from roads, railways, factories, and the like, it has been common to install a soundproof wall to block noise transmitted from a noise source. The noise reduction effect (soundproofing effect) of this soundproof wall is more effective as the height of the wall is increased. However, the cost increases, and the problem is caused by sunshine, landscape, ventilation, etc. Inconvenience may occur.

状に開口した補助防音板１１ａ、１１ａから形成され、
その両先端部分には、小形凸板１１ｂ、１１ｂが内側に
向けて立設されている。In order to cope with such a problem, as shown in FIG. 5, a method of installing a soundproofing device 11 having a substantially V-shaped cross section on the upper portion of a normal upright soundproofing wall body 12 has been proposed. For example, it is proposed in Japanese Patent Application Laid-Open No. 9-264409. This soundproofing device 11 is formed of auxiliary soundproofing plates 11a, 11a having a cross section opened upward in a substantially V-shape,
Small convex plates 11b, 11b are erected inward at both ends.

効果が得られる。It is said that the soundproofing wall provided with such a soundproofing device 11 has a better sound-reducing effect than a soundproofing wall having the same height and which is simply erected, for the following reasons. The noise propagated from the noise generating source passes over the upper part of the soundproof wall and spreads further to the outside world. At this time, noise such as multi-diffraction or interference near the upper part of the soundproofing device 11 including the auxiliary soundproof plates 11a and 11a is generated. Since the sound is reduced by the phenomenon, a sound reduction effect greater than a simple soundproof wall (straight wall) without a soundproof device is obtained.

ことをいう。[0005] The sound reduction due to multiple diffraction means that the distance between the tips of the auxiliary soundproof plates 11a, 11a is sufficiently larger than the width of the soundproof wall main body 12, so that the noise passing over is diffracted at two places. This means that a noise reduction effect due to diffraction attenuation similar to a thick barrier can be obtained. In addition, sound reduction by interference means that noise is reflected in a substantially V-shaped soundproofing device,
Sound reduction by causing direct waves and reflected waves to interfere with each other.

It is unavoidable that the expected soundproofing performance is reduced, and that they coexist with moisture, so that weeds can flourish from the seeds that fly, and that the soundproofing material, sound absorbing material or metal component that constitutes the soundproofing device There is a problem that corrosion and deterioration of the steel are accelerated.
