The therapeutic goal is to send a specific frequency to guide the brain into the desired state. Binaural cues are important for sound localization and separation of signals from noise ( Fitzpatrick et al., 2009). They were reintroduced by physicist Oster (1973). The brain can only identify the illusion if two receivers detect the tones ( Avan et al., 2015).īinaural beats are currently the focus of scientific interest after first being described by Dove and Moser (1839) Royal Academy of Arts and Sciences (2022) and then defined by Thompson (1877) as a convergence of signals transmitted from the auditory nerves to the brain. The brain combines information about sounds received by the ears and produces an auditory illusion, a frequency following response that operates by stimulating neuronal phase locking ( Avan et al., 2015). Two brainstem circuits compare the sound that is captured by each ear. Introductionīinaural beats (BB) are a perceptual beat frequency created by the brain in response to the differences between two audio beats captured by both ears ( Avan et al., 2015). The aim of this case study is to assess the effects of adding Binaural Beats (BB) to brown noise and to music on the brain and physiology of four study participants. These results are encouraging in terms of developing musical products incorporating BB to affect human neural rhythms and corollary states of consciousness and warrant further research with more subjects and different frequencies of BB and different music tracks. BB seem to have profound effects on the physiology of subjects and since the beats were not audible, these effects could not be attributed to the placebo effect. Most subjects also showed an improvement in Menlascan measurements of microcirculation or cardiovascular score, although the Menlascan scores and Big Five character assessment results were less conclusive. We were able to see this across several scores, F3/F4 Alpha Assessment and CZ Theta Beta, calculated from EEG readings, that indicated an increase in positive outlook and a relaxing brain, respectively, and scalp topography maps. We found through measuring brain wave activity that in fact BB seem to objectively induce a state of relaxation. The study used inaudible binaural beats (BB) to measure the ability of BB to induce a relaxed state. We recruited subjects with the focus on people who were stressed and needed a break to experience relaxation. 2Department of Family Medicine and Public Health, University of California, San Diego, La Jolla, CA, United States.1California Institute for Human Science, Encinitas, CA, United States.
