Brainwave entrainment is a relatively new technology that uses binaural beats to change
the frequency of your brainwaves.
Why do you want to do that?
Well, throughout each day we all go through several states of consciousness, especially
when falling asleep or waking up.
For example, when you fall asleep, you go from being awake(the beta state), through alpha
and theta, to delta, the sleep state.
Brainwave entrainment helps you get to any one of these states. For example, if you want to
go to sleep, you need to get to the delta state. Or, in hypnosis, the goal would be to get to the
theta state.
It works like this...
If you strike a tuning fork and then hold a second tuning fork next to the first, it will start to resonate
at the same frequency as the first.
So, by listening to a series of tones at the same frequency as your brainwaves and then changing
those tones, your brain follows and changes frequency also.
There are several machines, about the size of a walkman that are just for brainwave entrainment.
These are called sight-sound machines.
They usually include glasses that flash pulses of light in sync with the binaural beats of the
brain entrainment.
One thing to keep in mind is that you must be using stereo headphones or speakers for this to
work because the pulses in each ear are sometimes different and they phase out of sync in
certain areas, which helps to allow each sound wave to wrap around your skull to fully change
your brainwaves.
Currently, this technology is being used for everything from insomnia to ADHD and even stroke
recovery.
It's still in its infancy, but just imagine the possibilities!
