Feature

Acoustic foam does help to make sound waves less, and are a good solution for sound absorption. This is why it is used to treat a room with a lot of echo or reverberation. It helps to create an acoustically “sound deadening” effect for rooms, with a lot of bouncing sound waves.
Use 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.
