Aluminum Foam Acoustic Board

Sound-absorbing aluminum foam (insulation) board:

After closed cell foam aluminum plate punch processing, it can be made efficiently absorbing plate (φ2mm hole drilling rate of 1% to 3%), with excellent sound absorption properties, absorption rate of 40%-80%. Applied in high-speed railway, highway, building, tunnel and sound barriers along the way. Sound insulation board, aluminum foam sandwich panels made 17mm thick, within the scope of 100 hz to 1000 hz sound insulation is 22.6-38.6dB.

Pinhole composite aluminum foam sound-absorbing board:

Adding composite surface pinhole acoustic panels on the basis of the closed-cell foam aluminum, it can make high sound-absorbing material. This material surface is not flat, uneven structure and has many small chamber structure, both surface diffuse reflection absorption through it. and through the porous structures such as acoutic energy dissipation, with good sound-absorbing effect. It can be widely used in interior noise, sound-absorbing projects.
