Intrinsic is a site-dependent audio and light installation that explores minimal sound and audio perception through a slowly changing aural landscape. Dimensions of the space govern the configuration of the installation. A series of sustained sine waves are played through one full-ranged loudspeaker placed at one end of the space. The frequencies of the sine waves correlate to the dimensions of the space and create standing waves or room modes. A series of light tubes are hung from the ceiling. Each light tube, with fitted microphone, correlates to these varying amplitude resulting from the standing waves. As viewers enter the pitch-dark room, their eyes begin to slowly adjust to the shifting white light intensities that seem to be hovering in the space. Their ears perceive changing loudness of different electronic sound materials resulting from the way they navigate through the space.
Angie Atmadjaja is a sound artist currently working and living in the UK. Her work centres on quiet, abstract, minimal audio/visual installations that explore psychoacoustic and acoustic phenomena. By articulating pure sound materials such as sinewaves and filtered noise, she creates works that place viewers in a realm of pure experience where sound is perceptually tangible.
