1Pcs Black/Charcoal Soundproofing Acoustic Wedge Foam Wall Panel 2.5x30x30cm

Features:
-Products using polyurethane sponge material, through the special treatment to form a triangular groove shape, and then by the complex process of foam made of silencer, sound-absorbing, noise, shock absorber sponge material.
-It is filled with small gaps and semi-opening structure can absorb the incoming sound energy to attenuate the sound waves, reduce the interference and reverberation of the reflected sound and improve the purity of the sound. It is a high-performance product of sound-absorbing and noise-reducing materials.

Specifications:
Product Name: Acoustic panel
Model: 519164
Material: Polyurethane foam
Total Size: Approx. 30 x 30 x 2.5cm (Length x Width x Thickness)
: Black
Product Care: Vacuuming of dust

Applications:
1.Household noise control (walls, pipes, ceilings, etc.)
2.Noise management of entertainment venues (KTV rooms, partitions, ceilings, floors, etc.)
3. Office noise control (light walls, Room, etc.)
4. Industrial noise control (plant walls, roofs, , doors, control rooms, etc.).

Principle:
With a large number of internal and external connectivity of the pores and bubbles, when the sound waves into which can cause air vibration in the due to the viscous air resistance, air and hole wall friction, so that a considerable part of the acoustic energy into heat energy is consumed. In addition, when the air adiabatic compression, the air and the wall between the heat exchange occurs constantly, due to heat conduction, but also make part of the sound energy into heat.

Package Included:
1 x Acoustic Foam

Note:
-Due to the different display and different light, the picture may not reflect the actual of the item. Thanks for your understanding.
-Please allow a little differs due to manual measurement.
