Diane Hamilton: Zen, Meditation, and Development (Archived Interview)

Back in 1839, a physicist named Heinrich Wilhelm Dove noticed something odd about the way the brain handles sound. When two slightly different tones reach the two ears separately, the perceptual system responds in a particular way, producing an effect that exists in the listener rather than in the air itself. Dove was no fringe figure. He held a fellowship in the Royal Society and ran the Prussian Meteorological Institute, and he was the first to document what was happening.

Other people have since claimed a hand in the technology that grew out of that observation, but the original discovery belongs to Dove. The practical side came much later. Between roughly the 1950s and the 1970s, the effect he described was turned into a usable audio method, the kind now grouped under the term brainwave entrainment.

The idea applied here is simple enough: shape an audio stimulus so that it nudges the listener toward a calmer mental state, with mindfulness and relaxation as the goal. A recording built on Dove's finding is offered on this basis, meant to gently guide the brain into a more settled rhythm.

If you want the research rather than the claims, a search for terms like mindfulness and the psychological effects of brainwave entrainment will turn up published studies indexed on PubMed.Gov. That is where the data lives.
