Patented audio sound technology developped by Robert A. Monroe
and the Monroe Insitute
to help individuals achieve unusual states of consciousness
with the help of sounds.
Using two sligthly different sound frequencies
in each ears
, it is possible to influence the way the brain
works and to kind of "synchronize" the two brain hemispheres
. Different sound patterns can be used to obtain different effects. With the help of the Hemi-Sync sounds, it is easier to experiment different states of consciousness without the use of drugs or other control limiting means.
The Monroe Institute
conducts many scientific research on the Hemi-Sync technology. This is serious stuff!
