Binaural beats — what are they, how do they work and the functionality
Ever heard of Binaural beats? Well, a binaural beat is a perceived auditory illusion when two different pure-tone sine waves, both with frequencies below 1500 Hz, with a difference below 40 Hz between them, are presented the dichotomy to a listener (one through each ear), first discovered by Heinrich Wilhelm Dove in 1839.
However, Dove didn’t realize the full potential of this technology, he merely observed that it occurred.
Another 134 years passed before Gerald Oster wrote an article called “Auditory Beats in the Brain” that was published in Scientific American in 1973.
It has been suggested that a binaural rhythm occurs in the brain if you apply sinusoidal vibrations of a slightly different frequency independently, but simultaneously to each ear. This effect of heartbeat is created by the brain itself and is largely due to the structure of the brain’s internal wiring.
Now you might be wondering, what is the benefit of Binaural beats? Brain waves of different frequencies are associated with various mental states, such as deep meditation, dreams, working memory, and difficult thinking.
