Play this soothing white noise with binaural beats to achieve deep sleep. The binaural beats help induce delta waves in the brain, which is the brainwave associated with sleeping. This ten hour sound will help you achieve a night of great, restful sleep. Binaural beats work best when listened to with headphones.
Delta waves are a band of brainwaves that measure in cycles between .5Hz-4Hz on an EEG. These are frequencies well below human hearing (20Hz), so we need to "trick" the brain into being able to perceive cycles that low. Binaural Beats attempts to promote the creation of these brainwave frequencies by playing two different audible tones with a difference of the desired frequency, one in each ear of headphones. For instance, in my case, 53Hz and 55Hz, which has a difference of 2Hz, a Delta band frequency associated with deep sleep. This 2Hz difference intertwines inside the listener's brain which scientists believe causes it to synchronize with this 2Hz frequency. Neuro-Feedback theory suggests that the brain will recognize this 2Hz frequency as being associated with deep sleep, and will in tern, induce this state.
For this sound, I additionally added brownian noise to smooth over the dry tones. But I filtered them in such a way that they, too, contained a 2Hz frequency difference in each ear. So the brain should be perceiving a 2Hz phasing difference, from all sounds involved.
