Sound Proof Flooring Indoor Sound Insulation

Composite Metal Acoustic Panel:
The front and the back surfaces are made of inorganic materials with different densities and different thicknesses, the soft aluminum sheets are arrange in the core layer, and two layers of high polymer damping material are molded compositelyunder high pressure without adhesive the aluminum sheet in the core layer have obvious insulation property for medium-high frequency and ultra frequency sounds. And the high density boards on the front and back surface have good medium-high frequency sound insulation effect. The double-layer constrains damping structure generates high-frequency low frequency and ultralow frequency transmisssion shearing stress.

Sound insulation panel belongs to a composited acoustic material, Front and back use different density and thickness magesium board to form acoustic damping material structure which effective isolated low frequency and time low frequency sound transmission. Middle use demping material, take advantage of the resonance factors to prevent sound transmission.

Composite Damping Acoustic Panel


Composite damping acoustic panel double side using different density inorganic material, pressed with polymer impedance rubber, sandwich structure high pressure composite molding, forming a damping constraint structure. Which change the raw material resonance frequency and multiple increase material air sound reduction index and structure sound reduction index.



Characteristic: Magesium board never burning, is eco-friendly, good sound absorption function.
