"The perceptions of binaural beats involve cortical activity that is not different than acoustic beats in distribution and in the effects of beat- and base frequency, indicating similar cortical processing." - Pratt et al., 2010. Much of the research that does exist seems to be published in journals whose credibility I cannot vouch for, and this answer should therefore be taken for what it is: a cursory review of the best literature I could find, not as scientific fact.Īre binaural beats processed differently?
State of the evidenceīroadly speaking, some research on binaural beats does exist, but the evidence presented in the studies I examined is by and large negative, inconclusive or statistically underpowered with respect to the efficacy of binaural beats' ability to improve cognition, and to whether it is even processed differently from acoustic beats at all. When two coherent sounds with nearly similar frequencies are presented to each ear respectively with stereo headphones, the brain integrates the two signals and produces a sensation of a third sound called binaural beat (BB). For convenience, this is the definition of a binaural beat I will use. Since I was asked in chat about binaural beats, and have been posed this question a number of times before besides, I looked into the most recent literature using Google Scholar for the single term "binaural beats" and restricted my search to papers published between 2010-2015.
