Choices of binaural beats in PHOTOSONIX Systems
bb (binaural beats)
waver up and down in volume, and, as such, are
much more relaxing than strobe tones. Pioneering researchers, investigat-
ing the impact of sound on human behavior, developed beat frequencies
for precisely that reason.
Beat frequencies happen when two sound waves of different pitches occur
at the same time. The two pitches of sound interact with each other, and
the result is a new pattern, a sound wave which wavers up and down in
volume at the frequency that represents the difference in pitch between the
two sounds.
bbS (binaural beats with surf)
Many people have told us that it is one of
their favorite tones, because it is quite pleasing to the ear, and deeply
relaxing. You are mixing two of the most relaxing tones.
dbb (dual binaural beats)
dual binaural beats were first experimented
with by Robert Monroe. He used them to induce out-of-body experi-
ences. His main formula was to use combine a beta frequency to keep you
alert, with a theta wave, to induce a dream state. The idea was to induce a
state of mind awake, body asleep.
When it comes to dual binaural beats no one is exactly sure what state of
mind the combination of two brainwave states will actually produce.
Different people will have very different experiences with the same
combination. For that reason, Robert Monroe used a whole lot of different
combinations in his signature series, The Gateway Experience, so that
just about anyone would find a combination that work well for them.
You can do the same. If you experiment with dual binaural beats, you will
see what combinations work well for you.
