• Widely used as a material usually made of mineral or
cellular fibers. Sold in panels ranging from 12” x 12” up to 24”
• Usually made of synthetic materials, but also made from
wool,cotton or other fibers.
• Absorptivity is good only in high frequencies, and is based on
the thickness. Carpet absorbs sound, but can also attenuate
impact sounds since it prevents hard contact with floor surface.
NRC ranges typically between 0.20 to 0.55.
• Made by proprietary companies, (such as Serious Materials),
these panels are made of conventional gypsum and additional
sound-absorbing materials. Fairly expensive, approx. $40.00 per
