About Cymatics

Cymatics is the study of making vibration visible — classically, scattering sand or fine particles on a metal plate and watching them settle into geometric patterns as the plate is driven at different frequencies (Chladni patterns, first documented by Ernst Chladni in the 1780s and later extended by researchers like Hans Jenny). It's a real physical phenomenon: different frequencies produce different, reproducible standing-wave patterns.

This catalog uses “cymatics” more broadly, as an umbrella for research on any intervention defined by a specific frequency or pulse rate — sound, vibration, and ultrasound, but also electrical and magnetic pulse-frequency stimulation like transcranial magnetic stimulation (TMS) or remote electrical neuromodulation. What unites them is that the frequency itself is central to how the intervention is described and dosed, even though not all of them are things you can literally hear or feel — a device dosed by its pulses per second isn't always an audible tone. Where a mechanism has a genuine audible component, look for a Listen button on its card; where it doesn't (most electrical and magnetic stimulation, and most ultrasound), we say so rather than force a demo that wouldn't be honest. These interventions have very different levels of clinical evidence — see each entry's tier badge.

Tones are generated live in your browser (not recorded audio), so what you hear is the exact frequency, not a compressed or misattributed clip. Use a reasonable volume. Binaural beats need headphones — the effect only works with separate left/right audio.
