https://www.ntticc.or.jp/ja/archive/works/invertone/ In the space, 2 loudspeakers face each other, filling the entire space uniformly with white noise. Standing between them, the noise disappears precisely at the midpoint, where silence takes over. Opposite-phase waveforms emitted by the symmetrically facing speakers meet directly, canceling each other's sound and creating a kind of “blind spot.” “invertone” is an installation that allows visitors to experience the phenomenon of sound attenuation through mutual interference between phase-inverted sound waveforms in an anechoic chamber, a space covered in material that absorbs sound reflections. Its title combines “invert” (turn upside down) and “tone” (sound). In this work, sound, although invisible, is treated as if it were a fluid, immaterial “sculpture” made of frequencies. Frequencies appear as physical phenomena such as air vibrations and ripples in fluids, but we rarely have opportunities in everyday life to perceive and confront their existence. This work suggests that sonic phenomena involve physical and geometric mutual interference and indicates how human perception relates to this. The minimal space composed of repetitive sound-absorbing material and speakers, ready-made products, can also be said to speak eloquently of Nicolai’s distinctive aesthetic.
