Spectrogram measures and presents the frequency of sounds visually. The audience’s voices and background noises were converted into visuals, projected onto the drawing on the wall. The drawing is based on the spectrogram of machinery noises, created by playing scratched DVDs. The physical glitch of the machine translated into architectural imageries in contrast to the disorganised human voices. In spite of the visual differences, machine noises became equally indecipherable as human languages. The distinction between machinery noises and human language is our ability to understand our languages. Without comprehension, noises and language becomes intertwined.
