Binaural Beats And Their Benefits

Did you ever think there would be a non-drug and non-herbal orientated way to give yourself a more positive outlook, make you more energetic, more relaxed, or even control pain?
Well folks the good news is there is!
Its a sound technology called binaural beats and they are amazing.
Binaural beats are auditory brain stem responses that begin in the olivary nucleus of each half of the brain’s hemisphere. They result from the interaction of two different auditory impulses, originating in opposite ears, below 1000 Hz and which differ in frequency between 1 Hz and 30 Hz.For example, if a pure tone of 510 Hz is heard through the right ear and a pure tone of 500 Hz is heard through the left ear at the same time, an amplitude modulated standing wave of 10 Hz, the difference between the two tones, is experienced as the two wave forms mesh in and out of phase inside the olivary nuclei.
You Can’t Hear Binaural Beats But You Can Feel Them:
A binaural beat is not physically able to be heard because the human range of hearing is from 20-20,000 Hz. The sound is perceived as an auditory beat and theoretically can be used to stimulate certain neural rhythms through the frequency-following response (FFR)–the tendency for cortical potentials to stimulate or resonate at the frequency of an external stimulus. Thus, it is theoretically possible to utilize a specific binaural-beat frequency as a consciousness management technique to entrain a specific cortical rhythm.
Electroencephalography (EEG): This is the process of attaching scalp electrodes to and measuring the fluctuations from ionic current flows from the brain. This has been an effective tool in proving the effectiveness in the different type of binaural beats.
Different frequency’s of different binaural beats have various effects on the brain and can cause drastically different effects such as anywhere from an adrenaline rush, drifting you off to sleep, or even out of body experiences.
The chart below breaks down the wave name and frequency ranges as well as what they are associated with in the human mind:
|Frequency range||Name||Usually associated with:|
|> 40 Hz||Gamma waves||Higher mental activity, including perception, problem solving, fear, and consciousness|
|13–39 Hz||Beta waves||Active, busy or anxious thinking and active concentration, arousal, cognition, and or paranoia|
|7–13 Hz||Alpha waves||Relaxation (while awake), pre-sleep and pre-wake drowsiness, REM sleep, Dreams|
|4–7 Hz||Theta waves||deep meditation/relaxation, NREM sleep|
|< 4 Hz||Delta waves||Deep dreamless sleep, loss of body awareness|
From my personal experiences with these waves, alpha binaural beats have really helped me anxiety problems whilst using theta binaural beats has kept me focused, cool, and calm while in stressful work situations. The best part is that they will still work even if you play them in the background of actual music as a soft ambient noise (except for during deep states of meditation, so primarily for theta and beta).
Addition of Isochronic Tones:
If you want to get even more out of the binaural beats even i’d recommend trying to add in isochronic tones for a deeper and even more relaxing experience. Isochronic tones are essentially a repeating white noise similar to the repetition of a fan hitting air repeatedly or the soft static of no TV signal.
There are several variations on these frequencies out there so go try some for yourself and endulge in the glory of binaural beats.
My personal favorite binaural beat with isochronic tones to wake up to in the morning (make sure you play some techno or good house music in front of it). Enjoy
