sound installation

spectrum is a sound installation to explore the visual appearance of inaudible sound. This piece is comprised of the visual objects made of nano gratings whose internal structures express the sonic waves of ultrasound in different frequencies, and a light source. It illustrates the aesthetic properties of visible spectra which are naturally created from the artificially designed objects of the nano gratings. Each grating shows varied combinations of the spectral colour, depending on the internal structure of the gratings. Through this piece, the audience can ‘hear’ the inaudible sounds through unexpected visual outcome of natural reactions by electromagnetic waves.
