The 1839 Discovery Behind a Free Relaxation Recording

The audio effect at the heart of this recording goes back to 1839, when a physicist first noticed how a particular kind of sound behaves once it reaches the human perceptual system. His name was Heinrich Wilhelm Dove. He was a Fellow of the Royal Society and ran the Prussian Meteorological Institute, and he was the first to document what happens when the ears receive this specific auditory stimulus.

Plenty of people have since claimed credit for turning that observation into something usable. The practical audio technology built on it, though, really took shape across the 1950s through the 1970s. Dove himself got there more than a century earlier; the later work was engineering on top of a phenomenon he had already pinned down.

The free MP3 offered here draws on that same discovery. We took the stimulus Dove identified and shaped it toward two purposes: mindfulness and relaxation. The recording is meant to coax your brainwaves toward a calmer state. And yes, it costs nothing.

If you want to read past the marketing and see what the research actually says, a search for 'Mindfulness' alongside 'Psychological Effects of Brainwave Entrainment' will point you to published studies indexed on PubMed.Gov. We'd rather you look at the data than take our word for it.
