Specialty Fabrics Review | June 2013
Light-filled summer days and starry nights bring outdoor music events to parks and playgrounds, where tuneful performances float over audiences lazing on blankets and lawn chairs. One drawback to these idyllic outdoor concerts is sound quality, which is often unpredictable, diffuse and out-of-sync when channeled through multipurpose open stages.
During the London 2012 Olympic Games, two U.K. firms developed a solution—Soundforms, inflatable mobile acoustic performance shells that bring concert-hall sound into the great outdoors. Sound Forms PLC, London, is now the main contractor, designer and sales source for Soundforms.
Architen Landrell Associates Ltd., Chepstow, England, created the external skin for the eight inflatable cushions made with Precontraint 702 membrane that ensure waterproofing and form one structural Soundforms unit.
The sections, connected and sealed with the same air-tight zippers used in National Aeronautics and Space Administration (NASA) space suits, inflate to hold a curved clam shape.
The totally blackout Precontraint 702 stops the external light to come through and allows precise management of the stage lighting . The Precontraint dimensionnal stability is the key to maintaining the original structure shape.
