Dr. Eben Alexander is a practicing academic neurosurgeon for more than 25 years. On November 10, 2008, he was driven into coma by a rare and mysterious bacterial meningitis-encephalitis. Alexander awoke after 7 days to the surprise of everyone. He lost his memories of his life during the coma. His memory was filled with an experience of another realm of existence which Alexander felt was stronger than the earthly reality and soon recover completely.
Together with a few others, Alexander started a sound therapy program called Sacred Acoustics which makes use of the principles of brainwave entrainment to help himself and others reach and experience expanded states of consciousness which happened to him during the 7-day coma.
In the program, brainwave patterns are modulated to create a profoundly relaxed state.
Selected frequencies and tones were used to reduce the brain’s filtering and allows consciousness to become free. Each recording includes binaural beats, monaural beats, isochronic tones and other sound patterns which are combined to deliver a range of delta, theta and alpha rhythms to draw the brain into hypnagogia which is the transitional state between wakefulness and sleep. (Sacred Acoustics, 2017)
This program uses EEG to measure the brain’s electrical activity that is prevalent during deep meditative states and out-of-body experiences (OBE), similar to near-death experiences (NDE). Once recorded, the brainwaves are analyzed to extract specific combinations and ratios of brain states which are then converted to tonal formulas that are used to create complex combinations of monaural and binaural beat frequencies to create the higher states of consciousness desired.
