Mobile demountable stage designed to enhance the acoustics of outdoor performances
Designed to create the on-stage acoustic of a concert hall, the standalone stage, which is available in three sizes, is capable of being installed in three days and demounted in one.
The inflated fabric skin is supported on a lightweight aluminium frame, which rotates into position around an articulated pin joint, locked to a steel stage grid and weighed down with 26 tonnes of ballast to resist wind load.
The skin comprises eight white PVC-coated polyester cushions inflated to various depths by hoses connected to a low-noise AHU, which are attached to the frame with belts and buckles before being connected together with waterproof, airtight zips.
Sound is bounced towards the audience using geometry and a mixture of visible 18mm plywood reflecting panels, painted white, and acoustically transparent lycra screens with additional plywood panels behind.
