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.
Unlike to the traditional perforated acoustic panel, Bange perforated acoustic panel offer an invisible solution for the decoration, the surface of the panel is drilled with numerous tiny micro-perforations which can provide an excellent acoustical performance, mainly to trap the noise and reduce the reverberation time in the room. With 0.5mm micro-perforation, people will not notice any hole on the decorative board, keeping the finish completed.
There are various choises for the finish, melamin, HPL and veneer. 3 types of standard, 2-2-0.5, 4-4-0.5, 8-8-0.5, according to the different types, the distance of the distribution of the holes will be different, each square meter can approximately have maximum 140,000 holes.
