極めて効果がある。Further, by mounting the back side of the frame on the tunnel wall surface so that the back side air layer is formed by the sound absorbing plate mounted on the front side of the frame and the space on the back side, the back side air layer of the sound absorbing panel is formed. Easy to form and attach. As for the back air layer, the aluminum or aluminum alloy sound absorbing panel for tunnel interior of the present invention requires a space portion of about 5 cm as in the case of the conventional glass wool sound absorbing material panel. In the conventional glass wool sound absorbing material panel, the sound absorbing material has a thickness of 5 cm and the back air layer has a thickness of 5 cm.
Although it was necessary to secure an effective space of m, in the sound absorbing panel made of aluminum or aluminum alloy for tunnel interior according to the present invention, the sound absorbing plate made of sintered non-woven fabric containing aluminum or aluminum alloy fiber has a thickness of about 2 mm and a rear air layer. About 5 cm in total about 5 cm
The effective space is good, and the thickness can be reduced. It should be noted that the conventional glass wool sound absorbing material panel is about 10 cm in total,
The aluminum or aluminum alloy sound absorbing panel for tunnel interior of the present invention is about 5 cm in total, and the difference seems to be only about 5 cm. However, it is economical to make such a space in the entire length of the tunnel. Moreover, it is extremely effective in shortening the work period.
