Humans hear in the frequency range of 20 Hz to 20,000 Hz, however brainwave frequencies all fall below 40 Hz.īinaural beats are designed to correspond to one of the five brain frequencies: delta, theta, alpha, beta and gamma.

Depedning on the frequency of the beats, various places in the brain can become activated. It can also be achieved by those who happen to be extremely advanced when it comes to meditation.īinaural beats have been scientifically proven to have a direct correction to a person's spatial perception, as well as auditory recognition. The way a brain functions when it is exposed to binaural sounds is known as the frequency following response.Įntrainment, the process where a predominant brainwave frequency moves towards additional stimuli, is a practice that can be produced by binaural sounds. Still, most practitioners caution individuals with seizure disorders to check with their doctors before trying binaural therapy.Binaural beats, also known as binaural sounds, are repetitive notes believed to stimulate the brain and influence brain functions in ways that don't involve hearing.

However, he tells me that in the 25 years he has worked in the field, he has never heard of a single case of that sort. Leeds says that he has been told that in very rare instances someone with a tendency toward seizures could trigger an episode while listening to binary beats. I discussed this interesting issue with Joshua Leeds, a sound researcher and the music producer I worked with on my CD Sound Body, Sound Mind: Music for Healing, which features music designed to influence brain wave activity and encourage the body’s natural potential for healing. However, there’s at least a theoretical chance of running into trouble if you have epilepsy or an irregular heartbeat (especially if you have a pacemaker). Most people have no trouble with binaural beat therapy. (Monaural beats are already combined and don’t require headphone use.)

Over the years binaural beat therapy has been used to study hearing and sleep cycles, to treat anxiety, to induce various brain wave states and to promote relaxation and sleep.
