Soundproof panel and soundproof structure
A soundproof panel, that is configured with a nonwoven cloth structure, which contains wet heat bondable fibers, and in which these wet heat bondable fibers are fused to affix the fibers, and a board, is prepared. The soundproof panel may be a soundproof panel (1) in which a nonwoven cloth structure (2) and a honeycomb structure (3) are laminated. In addition, the soundproof panel may be a soundproof panel in which a first surface material and a second surface material are laminated on either side of a sheet nonwoven fiber structure. Furthermore, the soundproof panel may be a soundproof panel in which a first surface material and a second surface material are laminated with a quadrangular prismatic fill material made from the nonwoven fiber structure interposed therebetween. The soundproof panel is both lightweight and tough, and has excellent sound absorbing and sound insulating properties.
