![]() ![]() soothing music ,etc.) cannot give the same effect of getting down to, for example, Delta states (of 1- 4 Hz). The key thing is the brain cannot naturally “hear” very low levels of Hertz so normal pieces of audio (ie. It is known that many students have used binaural beats to help their concentration and help them recall information (which is invaluable for their revision). This is particularly useful, for example, in the mornings to wake up ready to meet the day or when you are doing physical exercise. ![]() 18 Hz) to stimulate more brainwave activity. Binaural beats can also be ‘targeted’ at higher brainwave levels (eg. This then graduates the persons brainwaves, in his case, to 4 Hz. If the binaural beat is 4 Hz, an increase in brain waves of 4 Hz occurs. This is equal to the Delta state which is synonymous with deep sleep.īrainwaves match or “follow” the binaural beat. Inside the head, the difference between the two tones is realized and a third “Binaural Beat” of 4 Hz is produced. He found that playing two coherent sounds of similar frequencies into each ear (using stereo headphones) could be made to produce a third “Binaural Beat” at the desired frequency.įor example, if a frequency of 100 Hz is played in one ear and 104 Hz is played in the other ear, a binaural beat of 4 Hz is created by the brain. Dove is credited with having discovering the principle way back in 1839. The sensation of auditory binaural beats occurs when two coherent sounds of nearly similar frequencies are presented one to each ear with stereo headphones or speakers.īinaural beats have been known about for many years. ![]()
