When a person is relaxed, alpha waves in the range of 8-13 hertz are produced in the brain. So, studies have been conducted using ranges up to 13 hertz to induce relaxation. Benefits have been seen for anxiety, nervousness and insomnia at these low ranges.
Beta and gamma brain waves have higher frequencies ranging from 14 to greater than 40 hertz. The boundaries between the ranges vary in scientific definitions. There is no universally accepted standard. But binaural tones are rarely intended to exceed the range of 40 hertz.
What Impact Do Binaural Beats Have on Memory and Concentration?
The studies that have been done concerning the question: will binaural beats help improve my memory and concentration, have yielded various results, as most scientific studies do. We know that beta brain waves are associated with being busy, active, aroused or concentrating. We know that gamma brain waves are associated with problem solving and higher mental activity. So, if a person wanted to try the binaural beats to see if there was a benefit for memory and concentration, the difference between the two tones should probably be between 30 and 40.
It is possible that the higher ranges could cause anxiousness in susceptible individuals. A person who has trouble concentrating because of an anxiety disorder, for example, is not likely to benefit from listening to the tones. He or she might, however, benefit from a more relaxing frequency, such as 10 hertz. Much has to do with the individual and what interferes with his or her ability to remember and concentrate.
So, if you ask, “Will binaural beats help improve my memory and concentration?” The answer must be “maybe”. It depends not only on the frequency used, but the individual’s brain chemistry and their neurological health.
When the beats are used to train the brain for any purpose, low volumes are generally recommended. As long as the beat is audible, research has shown that there is no benefit to using a higher volume. Since a higher volume can be unpleasant and could also contribute to hearing problems if excessive, it is always best to choose a lower volume.
