Binaural Beats For Memory and Concentration?
Will binaural beats help improve my memory and concentration? If so, how do they work? Here’s a brief discussion of the subject. You will find the answers to those questions and others below.
Binaural Beats Defined
The term binaural beat or tone refers to how the brain can take two sounds, one heard in the left ear, one heard in the right, and incorporate them into a single frequency in the brain. This incorporation of a single frequency has been shown to stimulate brain waves.
The frequencies used must be below 1000 hertz for the sounds to be perceived. By using specific frequencies of sounds in each ear, the frequency of specific brain waves can be mimicked.
Are Binaural Beats Audible?
Some people can hear the sounds. Others cannot. This phenomenon is not due solely to the person’s auditory or hearing system.
In the past, the tones have sometimes been used as diagnostic tools for neurological problems based on whether or not a person can hear the tones. For example, one physician and researcher on the subject found that people with Parkinson’s disease could not hear the tones, but after treatment began, they could. So, the tones were also used as a tool for gauging the effectiveness of treatment.
Not a great deal of research has been done concerning the question: will binaural beats help improve my memory and concentration. They might. They might not. Results have varied greatly in the tests that have been conducted. But some things have been learned.
The frequencies of brain waves range from less than four hertz to greater than 40 hertz. At less than four hertz, the brain is experiencing deep, dreamless sleep. There is a loss of body awareness. Waves of this type are classified as delta waves.
Brain Wave Frequencies and States of Consciousness
During meditation or at times when the body is very relaxed and also during dreamless sleep, brain waves are in the 4-7 hertz range. These are called theta waves. Binaural beats have been used successfully to induce a relaxed state. In order to accomplish this, the difference of the frequencies of the two tones must be somewhere between 4 and 7 hertz. Ranges less than 4 are rarely used, since this is the range experienced during deep sleep.
