matrix is a series of sound installations employing pure sine waves and white noises as a sculptural material. The installations are designed in response to specific gallery spaces or public sites selected by Ikeda. Sine wave are one of the purest forms of sound, white noise contains the full frequency spectrum randomly. As visitors pass through the sound field, subtle oscillation patterns occur around their ears, caused by their own movements interfering with the sounds. It is a very personal experience, and only through the visitors' physical engagement in the sound space can the real character of the work be perceived.
