SPIRRA SOFT – modular acoustic luminaire

13&9 DESIGN FOR WEVER & DUCRÉ

THIS ONE LIKES IT QUIET
We explored geometric, three-dimensional forms found in nature that – through their inherent geometry, such as the helical or convex and concave structures of shells – may have a positive impact on sound absorption. Our research indicates that such formations can be beneficial for room acoustics. Therefore, in our designs, we aim to translate the physical qualities of specific natural forms into sculptural, architectural lighting shades.

With SPIRRA soft, our focus was to create a functional, three-dimensional sound-absorbing surface. By thermally shaping a circular felt panel with a single cut, a spiral, spatially defining shade is formed. The clarity of the geometric form and the resulting angles enhance its acoustic performance.

SPIRRA soft is effective both as a single acoustic shade for a lamp and in combination with a second, oppositely mounted shade, which expands the spiral structure. This creates helical voids that further amplify the absorptive effect.
