Binaural Beats, in the simplest meaning possible, refers to a change in brain activity under the presence of an audio stimulus. Typically, binaural beats can be experienced when a person is presented with two different waves having different frequencies which are less than 1500Hz. In such instance, the brain produces a response which attempts to recognize the different in frequencies of the sound waves directed to it, and the binaural beats effect occurs in scenarios the difference in wave frequencies is less than 40Hz. The waves must also be presented dichotically for the binaural beats effect to be felt, that is, each wave passing through each ear.
How binaural beats work on the brain
When two signals having different frequencies are presented (one to each ear), the brain detects the phase difference between the signals. The information is processed somewhat differently as compared to when the signals phase differences are heard via speakers or stereo headphones. The perpetual integration of the two signals as perceived in the brain somewhat produces a sensation of another third beat. The difference observed in the two signals waxes and wanes as the two stereo sounds are made to mesh in and out of phase. Binaural beats thereby get to be perceived as a fluctuating rhythm.
How binaural beats create hypnotic response
Binaural beats can be heard at low frequencies that follow the EEG spectrum, typically at less than 30Hz. The phenomenon of binaural beating creates conditions which stimulate brain wave activity which in turn then alters that state of consciousness. Exposure to binaural beating is often associated with feelings of anxious thinking, active concentration, paranoia, arousal cognition. The feelings created can be harnessed for meditation practices and perhaps that could explain why the concept of binaural beats meditation is gaining rapid recognition.
The different states of consciousness that are associated with different frequencies of binaural beats
There are accelerated research efforts that reports on the consciousness level changes and their association to binaural beats. Binaural beats in the delta range (1-4Hz) are linked to associated reports of feeling relaxed, creative and being in meditative moods. Binaural beats in the delta range can thereby be applied to aid in states such as falling asleep. Binaural beats that fall between the alpha frequencies (8 to 12Hz) and beats that fall between the beta frequencies (16 to 24Hz) induces alpha activity on the brain waves and are thereby associated with reports of increased alertness, concentration and memory.
Harnessing the full power of binaural beats
In a nutshell, the brain simply utilizes the difference it perceives in the frequencies of the sound waves it perceives and creates a stimulation that corresponds to the waves frequency difference. Mind fitness can utilize the relaxing effect that binaural beats bring to the brain wave activity and thereby aid in progressive mental relaxation. The different frequencies of binaural beats (delta, beta and alpha) should be harnessed for different purposes since they induce different mental relaxation characteristics and their use should also be restricted to limited time spans. Following that approach ensures that binaural beats induce the mental state characteristic they are intended for.
