Research shows that binaural beats can literally drive brain activity into specific brain states (Gamma, Beta, Alpha, Theta or Delta). Without any effort and naturally, you would have your brain activity to synchronize with the binaural beat; it will become organized and coherent, and eventually, the left and right hemispheres of your brain will start to be balanced creating a very unique state called “hemispheric synchronization” (equal frequency and amplitude of the wave forms in both hemispheres). This extraordinary brain state is very powerful and normally unattainable without this kind of stimulation. Through the entrainment of brain waves, binaural beats can influence the brain in a very subtle way, inducing states of relaxation, sleep, meditation, creativity.
In 1839, the German physicist Heinrich Wilhelm Dove discovered that a person perceives acoustic shocks when two different tones from the left and right come to his ears. This discovery is called „binaural beats“. The biophysicist Gerald Oster then continued to research this phenomenon: in 1973 he demonstrated that the middle frequency, i.e. the compensating difference between the two tones, is generated by the brain. For binaural beats to occur, the stimulus frequency must be in the range of electrical brain wave activity, i.e. between 0.1 and 30 Hertz.
MONAURALE BEATS are a presentation of composite frequencies to one ear or both ears simultaneously which are demodulated in the cochlea. They are able to be perceived in either one or both ears.
ISOCHRONIC TONES are regular beats of a single tone that are used alongside monaural and binaural beats. At its simplest level, an isochronic tone is a tone that is being turned on and off rapidly. They create sharp, distinctive pulses of sound.
