Noise control
From Wikipedia, the free encyclopedia
In architectural acoustics, noise control refers to the method by which interior sound reverberation is reduced. Noise control is commonly employed to assist in soundproofing, or to improve a room's overall acoustics. Common noise control methods include the installation of acoustical gypsum, ceiling tiles, ceiling panels, carpet and draperies.
[edit] Noise Reduction Materials
Acoustical wall and ceiling panels can be constructed of many different materials and finishes. The ideal acoustical panels are those without a face or finish material that interferes with the acoustical infill or substrate. Fabric covered panels are one way to maximize the acoustical absorption. The finish material is used to cover over the acoustical substrate. Mineral Fiber Board, or Micore, is a commonly used acoustical substrate. Finish materials often consist of fabric, wood or metal. Fabric can be wrapped around substrates to create what is referred to as a "pre-fabricated panel" and often provides the best noise control if laid onto a wall, and require no modifications. Prefabricated panels are limited to the size of the substrate ranging from 2'x 4' to 4' x 10'. Fabric retained in a wall-mounted perimeter track system, is referred to as "on-site acoustical wall panels" This is constructed by "framing" the perimeter track into shape, infilling the acoustical substrate and then stretching and tucking the fabric into the perimeter frame system. On-site wall panels can be constructed to work around door frames, baseboard, or any other intrusion. Large panels (generally, greater than 50') can be created on walls and ceilings with this method. Wood finishes usually consist of punched or routed holes or slots and provide a warm and natural look to the interior space, although acoustical absorption is not as high.
