If we are in entraining the brain to 5 Hertz (Hz), both frequencies, the left and the right, are essentially carrier frequencies – because they are “carrying the signal”.īut it may be the case that we start off entraining the brain to 5 Hz, and then increase this to 7 Hz after 10 or 15 minutes. One frequency is sent to the left ear, and the other to the right ear. Let's go back to basics for a moment: To create a binaural beat we need two frequencies, a left and a right frequency. With that in mind, let's carry on and first define a carrier frequency. However, the Curve is a useful tool because it gives us a template from which to find where the optimal carrier frequency range is for a given frequency will be. He was concerned with level of perception, not optimal entrainment. Why? Because that is not what Oster was researching when he developed the Curve. Part of his research included the ‘Oster Curve', which is essentially a graph that shows which carrier frequency is optimal to hear binaural beats at specific frequencies. For example, the Curve recommends that Theta binaural beats should use a carrier frequency in the 160–210 Hz range.īut! We should note at this point that we can't take the Oster Curve as a literal guide to the best carrier frequency to use for optimal brainwave entrainment (using binaural beats). He published his research in a famous paper called “Auditory Beats in the Brain” (Scientific American, 1973). Oster did was open up people's minds to the fact that the natural phenomenon of binaural beats demonstrates to us that there may be other stimuli (other energy, awareness, higher consciousness) affecting the body that we aren't aware of. Finally, it is possible that hormonally induced physiological or behavioral changes too subtle to detect by ordinary means may be made apparent by measuring the binaural beat spectrum.Ĭonsidering the above, what Dr. The fact that sub- threshold sounds are effectively rendered audible by binaural beats suggests that there may be other stimuli processed by the brain of which we are not aware. Oster didn't invent binaural beats, or propose their use for brainwave entrainment that came later. He proposed how they might be used as a diagnostic tool for purposes related to health and science.Īs we explain in our article here, Dr. Gerald Oster, who pioneered binaural beats research in the 70s.
