2015 High Density Studio Acoustic Panels

The polyester fiber sound-absorbing decorative board is with functions of sound absorbing, mute, noise reduction, fire retardant, insulation and thermal insulation, solid uniform material. It does not only with the advantage of elasticity, toughness, wear resistance, impact resistance, non-cuttable, with great the cavity plate resonance sound absorption body effect. It is a wide band acoustic material of high efficiency.

In addition, the polyester fiber sound absorbing decorative board is light and of good material performance, unlike the other brittle materials, such as gypsum board or fiber cement pressure plate which easily generates falling rocks. The formaldehyde 0.05MG/1 emissions standards, is also far less than the state formaldehyde release quantity standard, which is less than or equal to 1.5. It is the replacement for the laminate and sponge or glass fiber new acoustic material, and is easy to be destroyed without polluting the environment, and can be recycled.

Absorbing Sound Principle of Polyester Fiber Board:

It is a material that has a large number of internal tiny connected pores inside. The sonic can be deep inside the material along these pores, and make material friction, which turns the sound energy into thermal energy.

It is a porous sound absorbing material, whose sound absorption characteristics are that the higher frequency sound absorption coefficient increases, the low frequency absorption is without high frequency absorption. The porous sound absorbing material is the necessary condition: the material has a large gap, gaps are interconnected and the material is deeply inside the pore.

One of the wrong understandings is that a rough surface material has the sound absorption performance. Actually it is otherwise, such as stucco cement, whose surface is the only stone that does not have sound absorption ability. Another wrong understanding is that material has large numbers of holes in the material, such as polystyrene, polyethylene, polyurethane, obturator that has excellent sound absorbing performance. In fact, these materials, because of the non-connectivity internal of holes, fail the sound waves to penetrate materials with internal vibration friction. Therefore, the sound absorption coefficient is very small.
