Binaural Beats are NOT a passing fad, but have been researched for over 170 years. The human brain goes through many frequency cycles every day, each frequency producing different effects in the human consciousness. Using this information, it has been discovered that the receiving and operating frequency of the brain can be altered and even controlled through the use of sound waves. Unfortunately, it was originally thought these waves were difficult or impossible to tap through sound waves since they happened beneath the 20 Hz range. Since that time, however, binaural beats have made it possible to hear what was previously thought unhearable.
