Abstract
Sound absorbency is imparted on a panel, which has increased strength and rigidity, by laminating a foam resin that is not originally permeable and does not absorb sound, and surface sheets that are not originally permeable and do not absorb sound. A sound absorption panel, obtained by laminating a foam resincomprising closed cells and aluminum alloy sheets(metal sheets), has a plurality of holesformed therein, which penetrate the foam resinand the aluminum alloy sheetsin the thickness direction. The holesare formed by forcing a needle(hole-forming means) through the foam resinand the aluminum alloy sheets
