Binaural beats were originally discovered in 1839 by German experimenter H. W. Dove. He discovered when signals of two different frequencies are presented separately, one to each ear, the brain detects
the phase variation between the frequencies and tries to "reconcile" that difference.In doing so, as the two frequencies mesh in and out of phase, the brain
creates its own third "phantom" signal—a binaural beat—equal to the difference between those two frequencies.
For example, if a frequency of 100 Hz is presented to the left ear, and a
frequency of 105 Hz is presented to the right ear, the brain "hears" a third frequency rhythmically pulsing at 5 Hz, the exact difference between the two frequencies.
Research has proven that introducing a binaural beat will cause the brain to begin resonating in tune with the frequency of that beat. This is called the Frequency Following Response and was discovered in 1973 by
biophysicist Gerald Oster at Mount Sinai Hospital in New York City. His research on binaural beats and the frequency following response was published in Scientific American and paved the way for further
development in the area of auditory stimulation to enhance brain functioning.
Since that time, binaural beat technology has been endorsed by scores of doctors and scientists around the world.
