Isochronic tones are regular beats of a single tone that are used for brainwave entrainment. Similar to monaural beats, the interference pattern that produces the beat is outside the brain so headphones are not required.
The Mechanism: Look at a light switch being turned on and off rapidly. Now imagine this with sound. That rhythmic pulse encourages your brain's electrical activity to sync up with the rhythm (entrainment).
Recommended Settings:
