What are Binaural Beats?
The sensation of auditory binaural beats occurs when two coherent sounds of nearly similar frequencies are presented one to each ear with stereo headphones or speakers.
The brain integrates the two signals, producing a sensation of a third sound called the binaural beat.
For example, if a frequency of 100 Hz is played in
one ear and 107 Hz is played in the other ear, a binaural
beat of 7 Hz is created by the brain.
Brain waves match or “follow” the binaural beat.
If
the binaural beat is 7 Hz, an increase in brain waves of 7
Hz occurs.
Binaural beats originate in the brainstem's superior olivary nucleus, the site of contralateral integration of auditory input.
The binaural beat is neurologically conveyed to the reticular formation which uses neurotransmitters to initiate changes in brainwave activity.

Consciousness
Beta (13-26 Hz) Alert concentration and problem-solving
Alpha (8-13 Hz) Alert relaxation
Theta (4-7 Hz) Deep relaxation and increased learning
Delta (1-3 Hz) Deep sleep
These topographic brainwave maps illustrate the state-changing potential of the process.
The image below shows the dynamic changes in the brainwave patterns from the initial state to the final coherent state.
