して使用する場合には良好である。By joining the back plate 6 to the sound absorbing plate 3 as in the present embodiment, the sound waves transmitted from the sound source vibrate the film 1 and most of the sound waves are converted into heat by the plates 2 and 2. The sound wave that has passed still remains in the space 7 between the back surface of the wave-shaped protrusion 3a formed between one wave-shaped recess 3b and the next wave-shaped recess 3b (wave-shaped recess when viewed from the back plate side) and the back plate 6. Thus, the sound wave is randomly reflected, interferes with each other, attenuates, and almost no sound wave passing through the back plate 6 can be eliminated, so that the soundproof performance can be further improved. Most of the sound wave from the side opposite to the sound source is reflected by the back plate 6 and returns. However, the slight sound wave passing through the back plate 6 is also reflected on the back surface of the waveform convex portion 3a in the same manner as described above. Since the sound is attenuated by being dispersed in the space 7 with the back plate 6, sound waves passing through the sound absorbing plate 3 from the side opposite to the sound source can be almost eliminated, which is favorable when used as a partition wall.

ができる。A hole 4c for screwing is formed at an appropriate position in the outward flange 4b on the outer periphery of the formwork 4. When the hole is used as a soundproof wall, it is screwed into its mounting portion or when it is used as a partition wall. Is used to connect panels. In the present embodiment, since the back plate 6 is joined to the back surface of the sound absorbing plate 3 and formed into a panel with the formwork 4 and the support rods 5, it is easy to install as a partition wall and used as a soundproof wall. In such a case, it is possible to save time and labor for processing on site, which is convenient. In addition, since the back plate 6 is translucent and the sound absorbing plate 3 is also composed of a pair of mesh-like metal plates 2 sandwiching the translucent sound absorbing film 1, the sound absorbing panel can be seen inside and outside, and the compression can be performed. It does not give a feeling and is good in view. From such a use, it is possible to provide a material optimal for use as a soundproof wall of an outdoor facility such as an outdoor pool or a stadium.
