20 Minutes Binaural Meditation Music
"Binaural beats, or binaural tones, are auditory processing artifacts, or apparent sounds, caused by specific physical stimuli. This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states.Binaural beats reportedly influence the brain in more subtle ways through the entrainment of brainwaves and provide other health benefits such as control over pain.
Binaural beats may influence functions of the brain in ways besides those related to hearing.
This phenomenon is called "frequency following response". The concept is that if one receives
a stimulus with a frequency in the range of brain waves, the predominant brainwave frequency is said to be likely to move towards the frequency of the stimulus (a process called entrainment). In addition, binaural beats have been credibly documented to relate to both spatial perception and stereo auditory recognition, and, according to the frequency following response, activation of various sites in the brain.
When the perceived beat frequency corresponds to the delta, theta, alpha, beta, or gamma ange of brainwave frequencies, the brainwaves entrain to or move towards the beat frequency. 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. An experiment with binaural sound stimulation using beat frequencies in the beta range on some participants and the delta/theta range on other participants found better vigilance performance and mood in those on the awake alert state of beta-range stimulation.
Binaural beat stimulation has been used fairly extensively in attempts to induce a variety of states of consciousness, and there has been some work done in regards to the effects of these stimuli on relaxation, focus, attention, and states of consciousness. Studies have shown that with repeated training to distinguish close frequency sounds that a plastic reorganization of the brain occurs for the trained frequencies and is capable of asymmetric hemispheric balancing.
