- Interactive Sound Installation
Cymatics is a kinetic sculpture and sound installation that expresses the artist’s vision of nature through a series of symbolic elements that are used harmoniously in a technological context.
A place where art is a bridge between the material and the spiritual, between technology and nature, and between the humanities and science. Two cubes, two rooms, two substances – water and non-Newtonian fluid– are brought together into spaces where sound waves transform the substances into geometric shapes. The result is a harmonic vision of the elements of nature, demonstrating the morphogenic effect of sound waves (cymatics).
The main materials used in this installation are a speaker and liquid. The vibration of the sound by the speaker is transmitted to liquid, and it expresses as wave motion. The liquid consists of water and Non-Newtonian Fluid (which contains water and the cornstarch). The sound is generated by a computer, and the liquid makes a pattern by the speaker that vibrates. The spectator, who visits the installation, creates this pattern depending on the choices of buttons on iPads. In another word, this can be said the interactive sound installation. The emitted sound is not only to be listened, but also it is perceived to man's body as a vibration by subsonic frequency. It is also shown physically as a natural phenomenon in the liquid. Therefore, it is a type of a new installation that one can actually experience visual and aural phenomena, and extrasensory that exceeds beyond our knowledge.
About the liquid and the vibration
When the sound from the speaker is in lower frequency (subsonic frequency), many round circles are periodically created in water. The interval in the line of the circle gets narrower, when the frequency rises higher. As the volume is louder, the height of the wave becomes higher.
On the midrange frequency, it becomes a distorted wave motion. When a sound is a noise, the phenomenon in which the whole water surface rages, happens. When the frequency of sound and the resonant frequency of a container coincidence, the Resonance phenomenon will be caused in the water, as well. When the oscillating frequency of a wave motion and a container resonate, it becomes big energy, and a spray begins to occur. Furthermore, when volume is enlarged, a spray will fly even to a spectator.
For example, cornstarch and water can be mixed.
When it's weak sound in medium frequency, waves are created. The form will not be able to be predicted, when the sound is loud with lower frequency, and the form will be like many monsters that begin to stand, when the sound is louder. It will be certain that the spectator begins to be surprised, when it begins to move in this form of monster.
Sound is transmitted to man's ear by air vibration from the speaker. Electric signal is changed with the magnet of speaker to physical vibration, and this oscillating part makes it change to vibration of air. By contacting a liquid and powder in the oscillating part, vibration which can not be usually seen, can actually be seen as physical reaction. For a periodic motion, the liquid also serves as a periodic pattern. If sound is simple, it will become a clear pattern. A pattern will also become complicated, if a sound is complicated. Vibration changes by the sound and the wave and pattern change with the vibration in natural physics. A spectator can hear sound, but can feel the vibration with the body. The physical feeling can be also seen as a wave depending on the substance of liquid simultaneously. It is quite interesting to observe closely this natural phenomenon which is artificially made depending on the public's operation.
The author has so far recited the concept of “the music to see and the visibility to hear”. The relation between hearing nature and visibility was considered and it has pursued on a work. It can be heard, but also sound can be experienced as vibration and can be materialistically seen here. The complexity of man's perception is re-recognized anew here, and it re-expresses on this work as interactive installation here.
