Sleep Music With 4.5Hz Isochronic Tones

Isochronic tones are single tones that come on and off at regular, evenly spaced intervals. This interval is typically brief, creating a beat that’s like a rhythmic pulse. They’re often embedded in other sounds, such as music or nature sounds. Isochronic tones are used for brain wave entrainment, in which your brain waves are made to sync with the frequency that you’re listening to. It’s believed that syncing your brain waves to a certain frequency might be able to induce various mental states.
