iDosing - Scam, Placebo or Real?
While brainwave entrainment is well proven using isochronic tones and monaural beats, entrainment via binaural beats is minimal. Binaural beats certainly cannot produce the effects of consuming illegal drugs. Binaural beats are perceived by presenting two different tones at slightly different pitches (or frequencies) separately into each ear. This effect is produced in the brain, not in the ears as with monaural beats. It is produced by the neural output from the ears and created within the olivary body within the brain, in its attempt to “locate” the direction of the sound based on phase.
Binaural beats are not very noticeable because the modulation depth (the difference between loud and quiet) is about 3 db, a two-to-one ratio. (Isochronic tones and monaural beats easily have a 50 db difference between loud and quiet, which is a 100,000-to-1 ratio.) This means that binaural beats are unlikely to produce any significant entrainment because they don’t activate the thalamus. But they do have some hypnotic and relaxing effects by way of dissociation (as does white noise and music).
