|Fire resistance:||China Standard Class B1||Thickness:||12 / 15 / 18 mm|
|Product name:||Perforated acoustic wall panels||Surface:||Melamine,Veneer|
1 Perforated wood acoustic soundproof wall panel is a kind of resonance absorption material with holes through on the quality MDF board.
2 It has strong selection on the sound spectrum and particular great performance on the middle and low requency.
3 If filled with the acoustic cotton at the back side space of the acoustic panel, it has better performance on the middle and high frequency.
4 The holes diameter and pitch can be custom made.
5 Strong impact resistance, excellent decorate performance, elegant color, especially work for wooden construction.
Perforated acoustic panel : BANGE perforated acoustic panel used high density mold- proof, fireproof, enviromental eco-pine wood as base material, processed by full automatic computer controled equipment. Be made to multihole structures product, not only have good sound absorbing effect, but also looks great on visual.

1> First fix the aluminum profile onto the wooden frame or bottom board, and their distance suggested 6about 600mm.
2> Filled the 32-64kg/m density acoustic foam among aluminum profiles.
3> Use the clips to fix the perforated acoustic panel to the aluminum profile.
4> When install several acoustic panel, the distance between noses to noses suggested 2-3mm.
5> If install the acoustic panel in the horizontal way, then the notch of the panel should face down, and it need to be fixed tight with clips. After that install pieces and pieces of acoustic panel onto the lowest one.
Perforated wall panels performances:
Acoustic absorption is usually defined in terms of an absorption coefficient(usually denoted by the Greek letter alpha, α), defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain material. Absorption coefficients range from 0 to 1 and vary with frequency, α=0 means that the material absorbs no sound and reflects all sound energy incident on it.
α=1 means that the material absorbs all sound energy incident on it and reflects none. Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound. In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.
As you can see our Testing report show that our products have a very good performance in a
large range of application.
