I researched a little about
mental entrainment on the
internet and found out what it was.
The best I can describe it is that you'd use either something called "brain machines", where you're accosted visually with flashing pulses of light, or
binaural sound, which plays different frequencies of sound on earphones.
I, of course, had chosen
binaural sounds. (I did try the lights and they gave me a headache!)
The
binaural sounds play two tones, one in each ear of your headphones.
It seems that human ears can't hear frequencies below 30 Hz so they have to be "perceived" by the brain.
One tone played a frequency of 310 Hz and one tone played a frequency of 300 Hz. Now the difference between these two frequencies is, of course, 10 Hz. That is both below what my ears can hear and is the same frequency that exists normally in my brain when I'm completely relaxed (which isn't often!).
Now the
mental entrainment part takes place.
It seems the brain will "entrain" or fall into step with the frequency it hears. In this case it is 10 Hz. Now, remember, my brain is operating at somewhere around 40 Hz plus 'cause I'm always stressed!
The brain will then gravitate to that 10 Hz frequency of relaxation.
Well,
dadgum if I didn't feel like I was at the beach, reading, listening to the waves. I honestly felt more relaxed than I'd been since vacation. It was really cool.
