Specification
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.
