let's conduct a simple experiment best done with a set of stereo headphones okay you ready i'll
play a tone at 95 hertz this sound wave is pulsing 95 times a second here's another tone at 88 hertz
if I play both sound waves together each through a different speaker you'll notice
that they create a slow pulsating sound of a lower frequency the resultant sound wave has a
frequency equal to the difference between the two applied sounds here creating a 7 hertz waveform
these waveforms have many names and they all demonstrate one key principle in physics
energy is neither created nor destroyed when two waves interact together they combine into a lower
frequency wave with a max amplitude equal to the combined amplitude of the two waves
your left and right outer ear is funneling these two sound waves into each ear canal
and your eardrums are vibrating with these waves each slightly out of phase with the other
connected to the eardrum are three tiny bones inside the ear known as the ossicles which
vibrate at that same frequency as the sound wave and amplify it on its way to the cochlea
the cochlea is the size of a small pea and is filled with fluid sound waves traveling
better through water inside the cochlea stereocilia sit at the top of hair cells
as groups of stereocilia oscillate with the sound waves propagating through the cochlea
they emit ions which cause the release of neurotransmitter chemicals at the base of
the hair cells they rest on right now during this experiment neurotransmitters in each of
your cochleas is pulsing an electric signal to your brain at the frequency of the sound wave
being provided to each ear when binaural beats are played through headphones your dense skull stops
the two sound waves from combining directly into a lower frequency acoustic beat but you still hear
the pulsing don't you this happens because the electrical signals from each ear combine into one
electrical signal on their way down the auditory nerve and the brain perceives the combined wave
as a sound we recognize and understand though that actual sound wave did not exist
only its inputs whether auditory stimulation is from an acoustic beat played outside the body
or binaural beat played with stereo headphones the physiology of the ear creates electromagnetic
waves of identical characteristics to that of the sound waves it captures and amplifies if
the acoustic or binaural beat is stable of a loud enough decibel and experienced for a significant
enough length of time then brainwave patterns change in response to the auditory stimulation
this experiment is using a 7 hertz binaural beat which is in the 4 to 8 hertz theta brainwave range
theta brainwaves are associated with creativity relaxation enhanced learning
and better memory people use binaural beats to change their brainwave frequencies for different
physiological and psychological effects the consciousness changing effects of binaural beats
are best experienced when in a calm state of mind meditation being best and with this video I hope
you were able to directly feel the effects of this experiment are you relaxed and have you remembered
what I taught you I think so as the 7 hertz binaural beat played during this demonstration
will have boosted your learning capability and enhance your memory by increasing theta brainwave

researched and taught by me if you would like to experiment more with binaural beats and with
different frequencies I have long tracks in my binaural beats playlist on the left
or you can continue the experiment by upgrading the seven hertz binaural beat into a 7.83 Schumann
Resonance binaural beat thanks for participating boost those brain waves and have a great day
