12 Hours Deep Delta Wave .25 Hz Binaural Beat For Extreme Meditation

Subwoofer or headphones required.

This is a very deep bass one quarter hertz delta wave designed to help with meditation sessions. Relax to the gentle throbbing created by this noise. Also useful for focus at other times, to aid in study, or to help with going to sleep.


A delta wave is a high amplitude brain wave with a frequency of oscillation between 0–4 hertz. Delta waves, like other brain waves, are recorded with an electroencephalogram[1] (EEG) and are usually associated with the deep stage 3 of NREM sleep, also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep.

  1. Is this really delta? On Wikipedia it says that delta is only .5, that it used to be accepted to only be 1hz but now .5z is the accepted number. Not that I'm complaining it's still great, just curious. I don't know much about the technical side of these binaural beats I just know I've been a fan of them for over 10 years

  2. Very soothing after a long day! I've been using this, the .5 Hz and the Schumann resonance videos and I'm very impressed. I've been cutting back on soda and caffeine in general and using these while i sleep (as well as drinking more water) is doing wonders for my restfulness and energy during the day.

  3. Is this actually a .25Hz sound or did you work that number out as the "net"/resultant frequency of two slightly higher ones? Just wondering because most equipment can't reproduce lower than 5-7hz, though I'd imagine a lower frequency could still bleed through to that range. Lowest-sounding vid I could find on YouTube, good job on that, but still curious about the exact frequenc(ies) in Hz.

  4. I commented that the .5Hz was good for sinus pain (with bass-responsive earbuds of course), but wow, this .25Hz instantly makes my sinuses vibrate and feel better even more. Amazing… Thanks again!
