<p>Provided is a ceiling panel with combined soundproofing and sound-absorbing functions. The ceiling panel includes an upper layer made of a synthetic resin plate with formation of a plurality of slit spaces; a lower layer provided on a lower part of the upper layer and consisting of at least one stacked paper layer having a plurality of holes arranged in an alternate manner with respect to each other; and a finishing part made of a metal plate with both ends bending upward to enclose the upper and lower layers, wherein a plurality of panel segments are arranged and installed in contact with the ceiling, and the upper and lower layers and the finishing part are of a square or rectangular or Y- or X-direction strip shape. The ceiling panel of the present invention provides the following effects: - Reduction of the resonance via use of different panel materials, by sequential stacking of a synthetic resin plate and a paper layer having the lowest vibration amplitude to prevent mechanical vibration and fixation of the resulting structure to a building's interior ceiling. - Prevention of the passage of sound through the formation of a plurality of slit spaces on a synthetic resin plate. - Sound absorption, sound damping and vibration reduction through the formation of a plurality of holes arranged in an alternate manner on upper and lower paper layers formed of, for example, corrugated cardboard or the like.</p> |
