SOUNDPROOF PANEL AND SOUNDPROOF STRUCTURE |
摘要 |
A soundproof panel comprising a nonwoven structural member and a board member is prepared. The nonwoven structural member comprises a thermal adhesive fiber under moisture which is melt-bonded to a fiber of the structural member to fix the fibers. The soundproof panel may be a soundproof panel 1 comprising a nonwoven structural member 2 and a honeycomb member 3 stacked thereto. Moreover, the soundproof panel may be a soundproof panel comprising a board-like nonwoven structural member and first and second surface members stacked to first and second sides of the board-like nonwoven structural member, respectively. Further, the soundproof panel may be a soundproof panel having first and second surface members stacked through a square-pole rail member comprising a nonwoven structural member. The soundproof panel of the present invention has toughness for the lightweight design and has excellent sound absorption and sound insulation properties. |
