Tested to ISO 354 and ISO 11654 standards.
The alpha Sabine coefficient (αw) is a value between 0 and 1 with αw 0 indicating total sound reflection and 1 indicating total sound absorption.
When used in a roller shade application, the sound absorption ratings are as follows:
| At low frequencies: | (around 200hz), the fabric absorption is about 0.21 αw. |
| At medium frequencies: | (around 500hz), the fabric absorbs up to half of the incidental sound energy for roller shades at 0.5 αw. |
| At high frequencies: | (above 2000hz) the fabric absorption is about 0.55 to 0.65 αw. |
The specific values depends on the gap behind the fabric. The following table shows the sound absorption characteristics for a roller shade with a 175mm gap compared to other common building materials:
