Plaid Shape Recording Foam Insualtion Foam

advantage:

Excellent acoustic foam panel which you are looking for Product description:Uses polyurethane foam as materials, after special treatment by equipment to the formation of concave and convex side of the wave shape, formed by the
complex process of silencing foam, sound absorption, sound insulation, shock absorption foam material
The internal filled with small voids and semi- openings structured
Acoustic theory:
It has a lot of pores and bubbles inside and outside, when the sound waves incident in which can cause vibrations in the air gap, due to the viscosity of air resistance, air friction with the hole wall, a considerable part of the sound energy into heat energy which is consumed
In addition, when the air adiabatic compression, the air continue to occur heat exchange with the hole wall, due to thermal conduction, also make part of the sound energy into heat energy
