摘要： There is disclosed a panel for use in soundproofing walls, having a base organization in which an aluminum foam board containing numerous open pores and a noise-insulating metal board are attached to either side of an aluminum honeycomb structure via adhesive sheets. The numerous open pores allow the aluminum foam board to absorb medium to high-frequency sound waves while many hexagonal cells in the aluminum honeycomb structure serve as air pockets in which resonance occurs to attenuate low-frequency noise of 500 Hz or less. Thus, with the ability of the noise-insulating metal board to prevent the propagation of sound waves, the panel can effectively absorb and block noise over a wide frequency range. The panel has the advantages of being semi-permanent in life span, highly resistant to corrosion and excellent in surface strength enough to be resistant to impact, generating neither hazardous articles nor dust, and being reusable.
