Sound Absorption The honeycomb-like cell structure of cork and the airspaces trapped in the structure make it an effective soundproofing material. A cubic centimeter, approximately 3/8” cubed, contains about 40 million cells. When sound tries to pass through it, it is trapped and absorbed. A thin layer (3/32”) will absorb 10dB of sound.

SOUNDSTOP sound deadening fiberboard is a high-quality, cost-effective solution to airborne sound reduction. SOUNDSTOP favorably increases both sound transmission class (STC) and outside inside transmission class (OITC) values of walls, ceilings, and floors by absorbing airborne sound vibrations. Megasorber's Patented Sound Absorption System. Innovative Megasorber soundproofing materials are engineered to be highly effective. Our patented technology makes it possible to have soundproofing products block out fire, fluids and dust: (U.S. Patent No. 8167085, Canada Patent No. 2674986, Australian Patent No. 2009206197)
