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.
Bunge Acoustic wall panels products are made by new type environmental protection materials. Now, they are the most mature woods of the replaced technology in the world. They do not need any process of the surfaces, such as, printing, veneering etc. They are waterproof, termite proof, anti-flaming, resistant to pollution. The color is individual and beflexible .
The products can be nailed, planed, and sawed etc strong points. Their indexes of environmental protection and anti-aging have already reached the international standards.
Bunge acoustic wall panels are broad-spectrum on constructions, building materials, decoration materials, furnitures and other industry fields. They can be processed to sound absorbing panels, woodiness ceilings, doorframes, window frames, fences, picture frames, stair treads, stair railings, different size of panels, indoor and outdoor wall panels, household necessities etc, hundreds varieties.
