Acoustic absorption is usually defined in terms of an absorption
coefficient(usually denoted by the Greek letter alpha,,
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,
means that the material absorbs no sound and reflects all sound
energy incident on it.
means that the material absorbs all sound energy incident on it and
Absorption coefficients of 0 and 1 are ideal values that do not
exist in reality because all materials reflect and absorb some
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.
Applications:Stadium ,auditorium, multifunction room ,studio and any other
places where seek for high acoustic requirement
