The Discovery of Binaural Beats
Heinrich Wilhelm Dove, a Prussian physicist, first observed the phenomenon of binaural beats in 1839, noting how slightly different frequencies presented to each ear produced a perceived third tone.
In 1973, biophysicist Dr Gerald Oster published a paper in Scientific American titled "Auditory Beats in the Brain", which demonstrated how binaural beats are processed neurologically and suggested their potential for clinical and diagnostic use.
"It is possible that hormonally induced physiological behavior changes may be made apparent by measuring the binaural-beat spectrum" - Dr. Gerald Oster
How Binaural Beats Work
In the same way that electrical equipment runs at certain frequencies, so does the brain. These frequencies are known as brainwaves and are measured in Hertz (Hz). When we are in high states of anxiety, the speed of our brainwaves increases. When we are relaxed, the speed decreases.
Binaural beats recordings work by sending a slightly different sound frequency to each ear through stereo headphones. When the brain hears these two separate frequencies at the same time, it hears and interprets them as one vibrating tone – a binaural beat.
The brain's interpretation is the difference in Hertz between the left and right tones. For example, if the left ear receives 200 Hz and the right ear receives 205 Hz, the brain is influenced toward 5 Hz brainwave activity, which is associated with the Theta state. This phenomenon is known as the frequency following response (FFR), where brainwaves tend to synchronise with the frequency of auditory stimuli.
Brainwave States
Delta
0.5 - 4 HzDeep sleep, regenerative effects, loss of bodily awareness
Theta
4 - 8 HzDream state, deep meditation, intuitive awareness, REM sleep
Alpha
8 - 14 HzAwake, focused on inner world, relaxation
Beta
14 - 30 HzAwake, focused on outer world, learning, productivity
Gamma
30 - 100 HzHigher mental activity, problem solving, consciousness
Try The Phenomenon Yourself!
Put on your headphones and experience a pure binaural beat. Listen with both earphones, then try removing one to hear the difference. The pulsating beat you hear with both ears is your brain creating the binaural beat frequency.
