This is the fifth instalment of the Hypersleep series, featuring relaxing deep sleep music and delta waves. These brainwave entrainment frequencies are administered through the use of both binaural beats and isochronic tones, which begin in the theta range at 5.5hz and ramp down to delta 0.5 hz over the course of one-hour. The next hour plays out this deep sleep delta frequency before the cycle repeats again at the two hour mark.
Headphones are optional. Simply listen as you fall asleep, setting the volume to a level which you find pleasant and non-intrusive.
