By now you should know that binaural beat therapy works by listening to two different tones in each ear which forces the brain to create a third tone (the binaural beat) and that binaural beat therapy is specifically designed to create the specific tone that is related to the result you wish to achieve.
Let’s simplify that a little, when you are tuning in to your favourite radio station on your new radio, you have to be at the specific frequency for the desired station before you will be able to hear anything that is being broadcasted, in the same way, binaural beats have to be at specific frequencies for you to experience the desired result, whether it be relaxation or the feeling of being alert.
There are five main frequency ranges in which the brain operates naturally, each binaural beat session is designed to target a specific range at a specific frequency, so if you are looking for binaural beats that will help you sleep, but you find that the one you are using is causing you to wake up with a migraine or you not able to fall asleep, it’s not necessarily true that the binaural beat therapy has failed, just that the specific session is at a frequency that is not suitable to the natural process of your brain.
Here is a list of the five frequencies and their ranges:
Delta Waves: These are frequencies below 4Hz where you will experience deep, dreamless sleep and be unconscious.
Theta Waves: Between 4Hz and 7 Hz are used for meditation and non-REM sleep.
Alpha Waves: Between 7 Hz and 13 Hz which are used for relaxing, drowsiness and REM sleep.
Beta Waves: Between 13Hz and 39Hz for active concentration, arousal and paranoia.
Gamma Waves: Higher than 40Hz used for high-level mental activity and problem solving.
Each human being is a unique individual, therefore if your best friend finds that a binaural beat session of beta waves at 13Hz or 29Hz is the best solution for arousal or focused concentration, you might find that at 13Hz you get a migraine and at 29Hz you feel paranoid, while at 15Hz you are aroused and at 33Hz you are able to achieve focused concentration.
