Binaural Beats – What They Are, How They Work & What They Can Do For You
Thursday, June 9th, 2011Binaural bests were first discovered in 1839 by Heinrich Wilhelm Dove. However, Dove didn‘t realise the full potential of this technology, he merely observed that it occurred. It was another 134 years before Gerald Oster penned an article called “Auditory Beats in the Brain” which was published in Scientific American in 1973.
It was proposed that a binaural beat occurs in the brain if you apply slightly different frequency sine waves independently but simultaneously to each ear. This beat affect is created by the brain itself and is largely due to the structure of the brain’s internal wiring.
These binaural beats are auditory brainstem responses, originating in the superior olivary nucleus of each hemisphere of the brain due to the interaction of the two different impulses.
The frequency of the two tones is between one and 30 Hz. Lets take the example that the difference between the two tones is 10 Hz. This 10 Hz difference is experienced within the superior olivary nuclei as a beat . The brain has a tendency, through the frequency following response, to resonate at the same frequency as the auditory stimuli being presented. In our example this would be 10 Hz, which is that frequency of the Alpha state. If we offer a binaural frequency of 5 Hz, the brain will begin to resonate with that and produce Theta brainwaves. If we present a binaural beat of 3 Hz, Delta brainwaves are detected. Alpha, Theta and Delta brainwaves are connected to altered states of consciousness that can be used to reprogram the subconscious mind, eliminate negative thought schemas and release emotional connection to memories.
In layman’s terms all this means is that you can relax, put on some stereo headphones and let your mind synchronize with the binaural beat frequency to create real measurable changes in your mind and body.
