Claims

[Scope of claim for utility model registration] (1) A porous aluminum sintered plate disposed on the front side, and a honeycomb core in which the ends of each through hole are close to or in contact with the back side of this sintered plate. A sound-absorbing panel characterized in that it is formed by laminating a grid material such as wood and a back plate disposed on the back side of the grid material. (2) The sintered aluminum plate has a porosity of 35 to 5.
0% and a thickness of 2 to 3 mm. (3) The sound absorbing panel according to claim 1, wherein the lattice material is a paper honeycomb material, an aluminum honeycomb material, or an asbestos honeycomb material. (4) The sound-absorbing panel according to claim 1, wherein the back plate is formed of a metal plate, and a bent side covering a grid material and a sintered aluminum plate is connected to the periphery of the back plate. (5) The back plate is formed of a metal plate, and has a bent side around its periphery that covers the grid material and the sintered aluminum plate, and the above-mentioned porous aluminum sintered plate is attached to the tip of this bent side. The sound-absorbing panel according to claim 1, which is a registered utility model, and comprises a presser side that covers at least a pair of opposing sides of the periphery of the plate.
