The following tools and materials needed:

• Chladni Plate (Instructions to assemble to be posted in a separate tutorial page)

• Audio Amplifier capable of 40 Hz and above, 325W @ 8Ω (though this wattage is not necessary for image generation, it was available to me), appropriate wires for hook up

• Audio Interface - I used a Focusrite Scarlett 2i4 2nd Gen

• Tone Generator, or audio source via computer - Online Tone Generator

• Custom Audio Cable - 1/4 TS to open pos/neg ends, used alligator clips to connect to speaker terminals

• Granule material for image extraction. Easily accessible from generic craft store: salt, sand, crushed watercolor paint, powdered fabric dye

• Heavy weight paper - I used 140 Lb watercolor purchased at Blick, cut to size of Chladni Plate (18’’x18)

• Etching Press/Table - a rolling pin would be able to obtain similar results, though in this first video, I have gained access to specialty equipment.

• Ear Protection

The step by step, basically:

With materials gathered and all audio tech hooked up to generate sound, sprinkle a generous amount of the granule material on top of the Chladni Plate. Begin with low volume output from the audio amplifier, and slowly work the volume upwards until granules begin to form a distinct pattern. Experiment with frequency and volume amount until desired pattern is exposed. Be sure to wear appropriate ear protection when exposed to high volume.

After settling on a visual pattern, mute the amplifier and carefully remove the stainless steel top of the Chladni Plate. Set the plate aside. Prep the Etching press, and soak paper, patting excess water from paper with a clean towel.

Set the stainless steel top of the Chladni Plate carefully in the center of the Etching press, making sure not to disturb the image. Granules can be held in place with a light coating of fixative spray, or hair spray if needed.

Lay paper, face down, on top of the plate, being sure to cover every edge of the plate with the paper. The dampened paper will stick to the image, and soak up any dyes, if dyes or colorants were used. Apply sheets of newsprint on top of paper to ensure no dye leaks when running through the press. Run the plate and paper through the press. Slow and even movement can help ensure the paper absorbs as much of the image as possible.

After the press has been run completely, lift paper by one corner, careful not to drag the paper across any remaining granules on the plate. Allow the print to dry face up. Spray with fixative or a polyurethane to lock in particles as desired on to the paper.
