Binaural Beat Technology (BBT) is an auditory neurophysiologic technique which uses auditory tones (often embedded in music)
dichotically via stereo headphones to manipulate brainwave activity. Using the Monroe Institute’s Hemi-Sync technology, a
double-blinded, randomized, repeated measure study was conducted to assess the effect of BBT (in the theta brainwave frequency)
on the cardiovascular (CV) stress response. A sample of 74 United States military service members (age 22-61) with complaint of
post deployment anxiety was randomly divided into two groups (music with BBT and music without BBT). Each group was exposed
to their respective intervention for a minimum of 30 minutes at bedtime, three times a week, for a total of four weeks. Participants
underwent pre and post 20-minute heart rate variability tests to assess the effect of using the technology. A 2x2 mixed Analysis of
Variance was conducted and found a statistical significant difference (F(1, 63) = 7.56, p=0.008 (η2=0.107) in the low frequency HRV
measures, whereas the Music with BBT group showed a decrease while the Music Only group showed an increase (Pre = 77.83, Post =
75.33 vs. Pre = 66.42, Post = 74.41). A statistical significant difference was also found in the high frequency HRV measures (F(1, 63)
= 7.56, p = .008 (η2 = .107) whereas the Music with BBT group showed an increase while the Music Only group showed a decrease
(Pre = 22.17, Post = 24.67 vs. Pre = 33.58, Post = 25.94). Finally, the Music Only group showed a significant decrease (F (1, 57) = 4.39,
p = .041 (η2 = .072) in Total Power HRV measures when compared to the Music with BBT group (Pre = 2098.90; Post = 985.26 vs.
