A Vexing Problem Yields Unexpected Gifts: Wondrous Images of Vibrations

Since we first wrote about the mysterious mechanical vibration that shakes us awake at night, we’ve tried endless fixes to no avail and at times, have despaired of finding a solution. But amidst this difficulty have come many unexpected gifts, in the form of strangers reaching out to help, and research leading to rich layers of information about sound, acoustics and materials, and seeing our own tenaciousness in the face of a problem.

The latest gift came as we were following more trails about how frequencies work, having learned the specific freqencies of our vexing vibrations. We stumbled on a trove of startlingly beautiful images of vibrations
made on a Chladni plate, first devised in 1787. Fine powders are sprinkled on a metal plate that is made to vibrate; they settle into unique patterns determined by their frequency.

All provide a kind of comfort; we know that the irritating vibration is also a harmonic capable of great beauty.

    You’re quite right! I used some hi-fi amp and my iPhone to generate the signals. It wasn’t that great a setup as the speaker under the plate kept blowing fuses!
