Sound and light patterns can influence the rhythms of the brain, and that is a field that many people explore for relaxation, focus, or altered states of consciousness. If you’ve heard the terms brainwave entrainment, binaural beats, or isochronic tones, this is what they are referring to.
But do they actually work? I decided to run a personal experiment. My question was simple: what does brainwave entrainment do in my own brain?
To get any useful answers, I first had to measure how my brainwaves behave under ordinary circumstances. Only then could I compare them to what happens when I listen to isochronic tones, binaural beats, and audiovisual entrainment tracks.
This page is an index of all the sessions I’ve recorded and analyzed in the process.
In short, the results are clear: these entrainment tracks do alter my brainwaves in ways that don’t appear under normal conditions.
