Acoustical Properties of Suroflex-Products

AbSorFace:

As an acoustically effective cover fleece, AbSorFace raises acoustical absorption over a wide frequency range. The comparison of results of measurements of acoustical absorption within Kundt’s tube of Surobond without and with AbSorFace illustrates this:

AbSorFace ultra:

Compared with AbSorFace, AbSorFace ultra increases acoustical absorption in the lower frequency range, while the upper frequency range shows a more significant decrease. This is shown in the following diagram:

Densities vs. Acoustical Absorption

Acoustical absorption in relation to densities of our products is shown in following diagram. Surobond Plus, whose density and absorption was set to 100%, was used as a comparison.
