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:

Note: Suroloft is equipped with AbSorFace as standard, the variant without AbSorFace is for reference only.

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.
