Brain waves and Frequencies
When the perceived beat frequency corresponds to the delta, theta, alpha, beta, or gamma range of brainwave frequencies, the brainwaves entrain to or move towards the beat frequency. In other words, applying a stimulus to the brain will eventually bring the brain's state closer to the stimulus frequency.
Frequency Range, Name and Association
- > 40 Hz; Gamma waves; Higher mental activity, including perception, problem solving, fear, and consciousness.
- 13–40 Hz; Beta waves; Active, busy or anxious thinking and active concentration, arousal, cognition.
- 7–13 Hz; Alpha waves; Relaxation (while awake), pre-sleep and pre-wake drowsiness.
- 4–7 Hz; Theta waves; Dreams, deep meditation, REM sleep.
For example, if a 315 Hz sine wave is played into the right ear and a 325 Hz one into the left ear, the brain is entrained towards the beat frequency (10 Hz, in the alpha range). Since alpha range is associated with relaxation, this has a relaxing effect or if in the beta range, more alertness.
Brain waves and Frequencies
BETA activity takes place when a person is wide awake. Frequency is 14 Hz per second and above.
ALPHA brain waves occur when a person relaxes. The Alpha rhythm is between 7.5 Hz to 13 brain waves per second.
THETA is a slow activity, and is represented by a frequency of 3.5 Hz to 7.5 Hz per second.
DELTA brain waves occur when the individual is sleeping. Its rate of frequency is 1.5 to 4 cycles per second.
Effects Caused by Binaural Music
Listening to binaural music can stimulate your brain in different ways! The only things you need are player, stereo head- or earphones and binaural music track of certain frequency. This topic describes some possible effects achievable by this.
Helping in meditation
While meditators have traditionally used several years to learn the techniques of meditation, you can here-and-now attain the same effect with brainwave entrainment. No special training or great discipline is required. Good meditation frequencies are in the alpha range, from 8Hz to 13Hz.
When a certain brainwave state is experienced and practiced over a period of time, the brain will "learn" the state change and it will become easier to self-produce the desired brainwave state at will. Thus, using brainwave entrainment, you can expect to get some of its effects later even without any external stimulus.
Reducing learning time
The theta state (4Hz–7Hz) has been found to increase learning capabilities. In fact, children spend more time in theta state than adults, which probably explains the accelerated learning capabilities of children.
Alpha frequencies are also useful for learning purposes. You can play language cassettes, subliminal tapes, etc. during an entrainment session for a maximum effect.
Reducing sleep needs
Some people have found that half an hour a day of the Theta state binaural music can replace up to 4 hours of sleep.
Treatment of certain mental diseases
Entrainment by binaural music is used in treatment of depression, low self-esteem, attention deficit disorder, drug and alcohol addiction and autism, to name a few.
Brainwave entrainment has also been found helpful in alleviating headaches and migraines.
Note that willingness and ability to relax and focus attention affects how effective the binaural beat stimulus is for inducing state changes.
Other Effect of Binaural
For example, that by using specific frequencies an individual can stimulate certain glands to produce desired hormones. Beta-endorphin has been modulated in studies using alpha-theta brain wave training, and dopamine with binaural beats.
Some people use them for lucid dreaming and even for attempting out-of-body experiences, astral projection, telepathy and psychokinesis. (Note that the scientific consensus is that telepathy and astral projection do not exist, and that out-of body experiences are purely internal mental phenomena. However, the role of alpha-wave activity in lucid dreaming is subject to ongoing research (consult Wikipedia on that matter) Alpha-theta brainwave training has also been used successfully for the treatment of addictions, for the recovery of repressed memories, but as with other techniques this can lead to false memories.
A trial of Delta binaural beat technology over 60 days has shown positive effect on self-reported psychologic measures, especially anxiety. There was significant decrease in trait anxiety, an increase in quality of life, and a decrease in insulin-like growth factor-1 and dopamine and has been successfully trialled to lessen hospital acute pre-operative anxiety.
The dominant frequency determines your current state. For example, if in someone's brain alpha waves are dominating, they are in the alpha state (this happens when one is relaxed but awake). However, also other frequencies will be present, albeit with smaller amplitudes.
The brain entraining is more effective if the entraining frequency is close to the user's starting dominant frequency. Therefore, it is suggested to start with a frequency near to one's current dominant frequency (likely to be about 20 Hz or little less for a waking person), and then slowly decreasing it towards the desired frequency.
Some people find pure sine waves unpleasant, so a pink noise or another background (e.g. natural sounds such as river noises) can also be mixed with them. In addition to that, as long as the beat is audible, increasing the volume is supposed not to improve the effectiveness, therefore using a low volume is usually suggested. One theory is to reduce the volume so low that the beating should not even be clearly audible, but this does not seem to be the case.
History of Binaural
Heinrich Wilhelm Dove discovered binaural beats in 1839. While research about them continued after that, the subject basically remained a scientific curiosity until 134 years later, with the publishing of Gerald Oster's article "Auditory Beats in the Brain" (Scientific American, 1973). Oster's paper was landmark not so much for its own new laboratory findings, but rather that in the way in which it identified and tied together the isolated islands of relevant research done since Dove, in a way that gave the subject fresh insight and relevance to scientific research.
In particular, Oster saw binaural beats as a powerful tool for cognitive and neurological research, addressing questions such as how animals locate sounds in their three-dimensional environment, and also the remarkable ability of animals to pick-out and focus-on specific sounds in a sea of noise (what is known as the "cocktail party effect").
Oster also considered binaural beats to be a potentially useful medical diagnostic tool, not merely for finding and assessing auditory impairments, but also (because they involved different neurological pathways than ordinary auditory processing) for more general neurological conditions. For example, Oster found that a number of the subjects he worked with that were incapable of perceiving binaural beats suffered from Parkinson's disease. In one case, Oster was able to follow one such subject through a week-long treatment of Parkinson's disease; at the outset the patient couldn't perceive binaural beats, but by the end of the week of treatment, the patient could hear them again.
Oster also reported (in corroborating an earlier study) that there were gender differences in the perception of beats. Specifically, women seemed to experience two separate peaks in their ability to perceive binaural beats that seemed to correlate with specific points in the menstrual cycle (one at the onset of menstruation, one around 15 days later), which led Oster to wonder if binaural beats could be used as a tool for measuring relative levels of estrogen.
Hemi-Sync is a trademarked brand name for a process developed at the Monroe Institute, used to create audio patterns containing binaural beats, which are commercialized in the form of audio CDs. Other companies have also created and marketed products based on the concept of binaural beats such as Holosync by the Centerpointe Institute.
Hemi-sync is a patented technology developed by Robert Monroe, founder of the Monroe Institute, and Monroe Products. Hemi-sync is short for Hemispheric Synchronization aka Brainwave synchronization. Monroe indicated that the technique synchronizes the two hemispheres of one's brain, thereby creating a 'frequency-following response' designed to evoke certain effects. Hemi-sync has been used for many purposes, including relaxation and sleep induction, learning and memory aids, helping those with physical and mental difficulties, and reaching altered states of consciousness through the use of sound.
The technique involves using sound waves to entrain brain waves. Wearing headphones, Monroe claimed that brains respond by producing a third sound (called binaural beats) that encouraged various brainwave activity changes.
Replicated, double-blind, randomised trials on anesthetised patients have found Hemi-Sync effective as a partial replacement for fentanyl during surgery. A similar study found it ineffective at replacing propofol however.
