Anti-condensation metal sponge sound absorber
The invention discloses an anti-condensation metal sponge sound absorber, and relates to the technical field of building materials. The anti-condensation metal sponge sound absorber comprises a metal sponge sound absorption layer, a cavity layer, a low-frequency absorption layer, a metal outer frame layer and a carbon fiber heating tube; the low-frequency absorption layer is arranged below the metal sponge sound absorption layer, and the cavity layer is arranged between the metal sponge sound absorption layer and the low-frequency absorption layer; the periphery of the metal sponge sound absorption layer and the periphery of the low-frequency absorption layer are fixed through a metal outer frame layer; and the carbon fiber heating tube is arranged in the metal sponge sound absorption layer. The anti-condensation metal sponge sound absorber has the beneficial effects that the sound absorption performance is continuously kept in the natural environment, the shock resistance is good, and the anti-condensation metal sponge sound absorber is non-combustible, light and capable of shielding electromagnetic waves.
