　　1. What is soundproof melamine acoustic foam?

　　Use melamine 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

　　2. What are the acoustic theory of soundproof melamine acoustic foam?

　　It has a lot of pores and bubbles inside and outside, when the sound waves incident in which can cause vibrationsin 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 .More Information about Melamine Foam Sponge 5cm Thickness Acoustic Foam Sponge
