HUMMINGBIRD demonstrates how curvilinear poles filter persistent sound.
By imitating nature — think of a tightly knit grove of trees — the poles create the conditions for a ‘sonic crystal’ acoustic metamaterial to filter and attenuate urban noise. In this short demonstration video, you can hear subtle ‘drop outs’ of sound, and shifts of pitch.
A colourful decoy applique attracts passersby; it visually morphs and ‘shape shifts’ as you circle the sculpture, and with every turn draws attention to the ‘sonic crystal’ sound effect.
HUMMINGBIRD sonic sculpture prototypes were made with the support of Edmonton Arts Council and Landscape Architecture Canada Foundation.
