Cymatics

This exhibit was inspired by Cymatics studies, a scientific term given by scientist Hans Jenny to a study aimed at visualizing sounds, where sound waves can be made visible by exposing some solutions or powders (such as water, sand, starch solution, etc.) scattered on metal surfac- es or Plastic, or even rubber membrane, to rear- range their positions to form consistent, periodic shapes that change as the frequencies they are exposed to change. Interaction: In this exhibit, the visitor controls two factors by moving two knobs; the first is for the frequency of the sound wave, and the second is for controlling the amplitude. After the interaction, the visitor will enter an exploration stage which involves his sense of hearing, seeing and feeling to connect the multiple variables to build an understand- ing of the nature of sound. The visitor will notice how a single material is responding to a range of frequencies, and how all three materials are re- sponding to a single frequency.
