The present invention relates to a sound-absorbing panel, comprising: a porous board; a glass fiber mesh attached to the bottom surface of the porous board; and a crushed stone powder layer formed in the pores and on the upper surface of the porous board. The sound-absorbing panel of the present invention is formed into a unique 3-layer structure for improving sound-absorbing function and durability, and eliminating the need for a finishing treatment on the crushed stone powder layer, which provides a significant economic advantage. In addition, the sound-absorbing panel incorporating the crushed stone powder layer provides superior heat resistance, humidity control and a deodorizer function, and is simple to manufacture and install. |
