MULTILAYER SOUND ABSORPTIVE PANEL
To provide a structure and manufacturing method for realizing a thick sound absorptive layer in which it was difficult to increase the thickness of the sound absorptive layer in a structure of honeycomb material whose cell space is filled with foam material as a sound absorptive layer, even though it is known that increasing the thickness of the sound absorptive layer is effective to increase the sound absorption coefficient in a sound absorptive panel.SOLUTION: A honeycomb material is filled with a foam material to form a sound absorbing panel, and a perforated material is disposed as a connection material between a plurality of sound absorbing panels to form a composite structure in which the sound absorbing panels are connected. An air-permeable material is disposed on one surface and non-air-permeable material is placed on the other surface, and the whole is adhered and fixed with an adhesive to form a multilayer sound absorbing panel.SELECTED DRAWING: Figure 5
【課題】吸音パネルにおいて吸音層の厚さを大きくすれば吸音率の増大に効果があることが判っているが、ハニカム材のセル空間に吸音層であるフォーム材を充填する構造においては、吸音層の厚さを大きくすることは困難であった。厚い吸音層を実現する構造と製法が課題である。【解決手段】ハニカム材にフォーム材を充填して吸音パネルとし、複数の吸音パネルの間に接続材として穴あき材を配置して吸音パネルを接続した複合構造とし、その片面に通気性材、反対側の面に非通気性材を配置して、全体を接着剤で接着して固定し、多層吸音パネルとした。【選択図】図５
