Ernst Chladi (1787) found a way to visualize sound waves by drawing a violin bow across the edge of flat plates covered with sand.
Margaret Watts Hughes (1885) invented the eidophone (a simple device which consists of a tube, a receiver and a flexible membrane) that translated the vibrations of her voice into patterns on a glycerin-coated elastic membrane.
Hans Jenny (1967) pioneered the study of wave phenomena, and named the art/science Cymatics. Using crystal oscillators (which allow precise frequencies and amplitudes to be used), he vibrated various powders, pastes, and liquids, and succeeded in making visible the three-dimensional effects of sound.
John Reid is an acoustics engineer, inventor of CymaScope, a machine which shows the complex structure of sound in a visual medium. He studied the acoustics of the King's Chamber in the Great Pyramid, where he stretched a membrane over the sarcophagus to reveal the harmonic structure of the 4-ton granite box.
Dan Carlson is a scientist, inventor and Nobel Peace Prize nominee. He invented the Sonic Bloom system for growing plants. He found that using sound frequencies between 3,000 to 5,000 kHz cause plants to absorb nutrients better. He holds a Guinness Record for growing the largest indoor plants in the world, the Purple Passion plant. (Purple Passion plants normally grow about 18 inches and live 18 months. Carlson’s plant grew to 1,300 feet and is still alive 25 years later.)
Dr. Masaru Emoto experimented with water crystals by exposing water in glasses to different words, pictures, or music, and then freezing and examining the shape and symmetry of the resulting crystals with microscopic photography. He claims that if the images will be beautiful or ugly depending upon whether the words or thoughts were positive or negative. These claims have been strongly criticized as "pseudoscience."
