Binaural Beats: What They Are & How They Work
Binaural beats are auditory brainstem responses originating in the superior olivary nucleus as a result of different frequency auditory stimuli provided to each ear. Listeners to binaural beats “hear” a beat at a frequency equal to the difference between the frequencies of the applied tones. Thus, the effect on the brainwaves depends on the difference in frequencies of each tone, for example, if 300 Hz is played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.
