Acousticalceiling tiles

• Widely used as a material usually made of mineral orcellular fibers. Sold in panels ranging from 12” x 12” up to 24” x 48”.

ACCOUSTICAL DRYWALL

• 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 4’x8’ sheet.
