SOUND ABSORPTION PANEL THROUGH USE OF CORE MATERIAL
PROBLEM TO BE SOLVED: To achieve a panel capable of absorbing sound from both surfaces with a simple structure, and to reduce the entire thickness of the panel.SOLUTION: A paper core layer 1 having a thickness tis formed by sandwiching, bonding, and fixing both surfaces of a sound insulation material 25 made of kraft paper between a first paper core material 4 and a second paper core material 4a made of kraft paper having many opening cores 5. An integrated panel 40 having respective layers laminated is constituted by bringing into close contact and bonding a first sound absorption layer 20 and a second sound absorption layer 30 having thickness tformed by compressing a special felt material to both surfaces 6, 6a of the paper core layer 1. The sound absorption panel is adaptive even if there are noise sources on both the side of the first sound absorption layer 20 and the side of the second sound absorption layer 30 of the panel material 40.SELECTED DRAWING: Figure 1
【課題】両面から吸音できるパネルを簡易な構造で実現し、パネル全体の厚さを薄くする。【解決手段】クラフト紙からなる遮音材２５の両面を、多数の開口コア５を有するクラフト紙からなる第１ペーパーコア材４と、第２ペーパーコア材４ａとで挟んで接着固定して、厚さｔ１のペーパーコア層１を形成する。ペーパーコア層１の両面６、６ａに、特殊フェルト材を圧縮して形成した厚さｔ２の第１吸音層２０、第２吸音層３０をそれぞれ密着させて接着して、各層が積層された一体のパネル４０を構成する。パネル材４０の第１吸音層２０側、第２吸音層３０側の両側に騒音源があっても対応できる。【選択図】図１
