Sound Absorbers are acoustical products that are unusually porous/soft surfaces that receive sound and help trap it before it leaves the product. These sound absorbers are typically used to treat the room they are applied in and help knock down reverberation or reflection off hard surfaces. They carry a comparative NRC number that helps determine the percentage of absorption at various key frequencies. Composite products are those that absorb reverberation and block sound and vibration from going to other areas.
