We have our acoustic products tested by SGS, a world leader in testing, inspection and
certification. That way the performance is measured, not just promised.
Sound absorption is expressed as an NRC value (Noise Reduction Coefficient) on a scale from 0 to 1:
the higher the number, the more sound the material takes in. With felt, mounting counts for a lot
— hanging the piece at a distance from the wall lets the material work on both sides and
increases absorption.
Less echo means more calm and better speech clarity. You can view the reports via the link below.
