What is “Delta” meditation? Delta has the lowest brainwave frequency between 0.5 and 4 cycles per second. Delta is produced during deep sleep, and is believed to be rejuvenating for the body..
This particular program progresses from the Root Chakra to the Crown Chakra, starts at a of 20.3 Hz (Beta) and ramps down gradually to a low Delta beat of 1.45 Hz, then ramps back up to 9.41 hz. Consequently, you should only use this at a time and place where it is OK to fall asleep. To take advantage of the binaural beats, you must use headphones, and be in a time and place where it is OK to deeply relax or sleep.
