How Canopies and clouds combine beautiful design with great acousticsSabinThe preferred metric for measuring acoustics for“space absorbers” like clouds and canopies.Total acoustical absorption for a suspended ceiling is calculated by multiplying theexposed surface area by the material NRC, while “space absorbers” are directlymeasured. Acoustical clouds and canopies can provide greater sound absorptionthan a continuous ceiling of the same surface area, because the sound isabsorbed from both the front and back surfaces.The installation of clouds or canopies in a reverberant space can significantly reducethe background noise and reverberation time, enhancing speech intelligibility.Exposed Structure Shapes Installation Continuous CeilingClouds & Canopiessound design Open Plan Building5,000 SF Exposed Structure(50' x 100'), 15' to deck,drywall with windows on twosides, commercial carpetCeilingNo Treatment(0% Coverage)ExposedStructureBe Sure You Get the Acoustic Values You SpecifyUL Classified Acoustics Since 1998Armstrong carries UL Classification for precise acousticalcompliance for three acoustical categories – NRC, CAC, and AC.As the industry leaders, Armstrong and UL teamed up in 1998to create this new classification to ensure more reliability inreporting and specifying product acoustical performance.This Icon identifies Armstrong UL Classified Acoustical ceilings – the assuranceof reliable performance in every ceiling panel. Be sure any panel you choose hascertified performance, or you may not get what you pay for.SoundScapes Shapes(50% coverage)156 Shapes:46" x 46" SquaresSabin/SF 0 1.49 0.90Reverberation Time (RT) 3.4 sec 0.9 sec 0.5 secRT Improvement ref 73% 86%SPL Reduction (dB) ref 4.5 -6.0For definitions of acoustical terms, see page 333 in this catalog.Made in United States of America by: Fabricado in Estados Unidos por: Fabriqué aux Etats-Unis par:Armstrong World Ind., Inc.
