These are generated sounds, specially designed to alter ones brainwaves generating a change in the state of mind, such as joy, creativity, or relaxation. They’re organically safe, non-addictive, and can be played as often as one needs to.

Scientists have been aware of certain frequencies that are associated with certain states of mind. Take for example the alpha frequency of 8 to 12Hz. This wave is accredited for the “superlearning”, positive-thinking modes which can usually be obtained through meditation. This can be verified through an electroencephalograph (EEG) reading.

The ears can typically pick up only those frequencies between 20 and 20,000Hz; those as low as 8Hz simply don’t register. If there was a way somehow to get the mind to hear those lower frequencies, such states of mental bliss could literally be commanded on demand.

That is exactly what Dove did. He found out that the inside brain can produce beats of a specific frequency that had direct influence on the brainwaves and ones state of mental state.

With the joint advancement of scientific research, complimented by EEG reading, these states of mind and their corresponding feelings or emotions have been identified as the object of binaural beat recordings.

Delta 1 – 3 Hz Deep sleep, dreaming, high level immune functions
Theta 4 – 7 Hz more relaxation, meditation and focus
Alpha 8 – 12 Hz Light relaxation and positive thinking
Beta 13 – 25 Hz Normal alertness and anxiety

Further studies have beefed up the concept that exposure to the featured frequencies is better at coaxing the desired state. A session that lasts more than 30 minutes at 5 Hz more than aptly substitutes around 2 to 3 hours rest from sleep. Insomnia can be remedied with a ten minute exposure to frequencies from 4 Hz and 6 Hz, and lowering it to below 3.5 Hz for twenty to thirty minutes, then dropping to 2.5 Hz and fading out. Accelerated learning, on the other hand, can take place when exposed to binaural beats from 7 Hz to 9 Hz.

These states of mind were reflected in EEG traces when the brain was exposed to frequencies below 30 Hz:

State Frequency Range State of Mind

  • Delta 0.5 Hz – 4 Hz Deep sleep
  • Theta 4 Hz – 8 Hz Drowsiness (also first stage of sleep)
  • Alpha 8 Hz – 14 Hz Relaxed but alert
  • Beta 14 Hz – 30 Hz Highly alert and focused

The dominant frequency in the EEG pattern determines what shall be called the current state of the brain. If the amplitude of the alpha range frequencies is highest, then the brain is said to be in the alpha stage. Note, that other frequencies still exist and it is impossible to give any “exact frequency your brain is operating on.” However, later references to the brain states use the simplification of assuming that such a single frequency exists.

Entraining the brain to a desired state

The right external stimulus can entrain or draw the brain frequency along from one stage to another. A person in the beta (highly alert) stage can drift off to full relaxation when exposed to a binaural beat stimulus of 10Hz. This is also called the frequency following response.

The nearer the brain’s state to the applied stimulus, the more efficient entrainment works. Executing a sweep from one frequency to another would be easier if the starting frequency is as close to the current brain state as possible. The sweep speed should be that your brain can switch easily. This can be determined with the aid of an EEG. Playing it by ear or by simple common sense would tell that during the day it can be assumed that the brain is in the beta stage (about 20Hz); the sweep can start safely from there. If the state is already somewhat relaxed, starting frequency can be set at 15Hz or a few Hz lower.

Treatment of certain mental diseases

Depression, low self-esteem, attention deficit disorder, drug/alcohol addiction and autism, have been reported to have been remedied by brainwave entrainment. The same goes for headaches and migraines.


Even sex drive has also been reported to have been addressed by brainwave entrainment.
