摘要： A porous sound absorbing structure 10 includes an exterior plate 1 and a closing plate 2 in order to suppress a decrease in sound absorbing performance in a wide frequency band. An interior plate 3 is arranged between the exterior plate 1 and the closing plate 2, and air layers 4 and 5 are located between the exterior plate 1 and the interior plate 3 and between the interior plate 3 and the closing plate 2 respectively. The exterior plate 1, the interior plate 3, and the closing plate 2 are arranged while opposed to each other. Many through holes 1a and 3a are made in the exterior plate 1 and the closing plate 2 respectively. In the interior plate 3, a plate thickness t2 and a diameter φ2 and an aperture ratio β2 are set so as to generate an viscous effect in air passing through the through hole 3a. The aperture ratio β1 of the through hole 1a in the exterior plate 1 is set more than 3% and not more than 50%.

摘要： 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 1, obtained by laminating a foam resin 20 comprising closed cells and aluminum alloy sheets 10 (metal sheets), has a plurality of holes 30 formed therein, which penetrate the foam resin 20 and the aluminum alloy sheets 10 in the thickness direction. The holes 30 are formed by forcing a needle 40 (hole-forming means) through the foam resin 20 and the aluminum alloy sheets 10.

摘要： The present invention relates to a silencer easily cleanable inside. This silencer comprises a casing cylinder and a segment member housed in the casing cylinder to constitute a sound reducing means. The silencer further comprises a segment member fastening means for fastening the segment member to the casing cylinder, a gas inlet-side lid plate with a punched hole, which closes an opening at one end of the casing cylinder, and a gas outlet-side lid plate with a punched hole, which closes an opening at the other end of the casing cylinder. At least either one of the gas inlet-side lid plate or the gas outlet-side lid plate is adapted to be detachable from the casing cylinder.
