DIFFERENCE BETWEEN BINARAUL / ISOCHRONIC / MONAURALE BEATS

BINAURAL BEATS are a presentation of neighboring frequencies to each ear separately for example 240 Hz tuned to the right side and 248 Hz tuned to the left side. The two hemispheres of the brain function together to “hear” and perceive not the external sound signals, but a third phantom signal. The difference of 8 Hz (e.g. Thetawaves) is processed in the medial superior olivary nuclei. An action of both ears is required for an effective brainwave entrainment. This resulting signal, discovered in 1839 by Heinrich Wilhelm Dove, is called “binaural beat”. 

 

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.

RECOMMENDED USE

There are no wrong ways in working with Binaural Beats and Frequencies. Do what comforts you the most and feels right. Use the frequencies you are drawn to and listen to them as long as it pleases you. Listen to your selected frequency a few times a week if not everyday for  at least 15-30 min. The brain needs between 5-8 minutes to get used to the selected Brainwave. If you choose a Binaural beat type it could be useful to work with headphones for improved results. It is possible to use your selected frequency in the background for example while studying or with full concentration towards the music for example while meditating. Find your own pleasing volume setting. When starting out it may be better to listen to frequencies affecting the lower chakras and visualizing their colors and working your way up.

SAFETY INSTRUCTIONS

Don’t listen to Binaural Beats while driving.
