The purpose of this prospective, double-blind, repeated measures study is to assess the efficacy of Binaural Beat Technology (BBT) on anxiety and anxiety related cardiovascular measures as well as to assess the feasibility of implementing a BBT intervention in a military population during the high risk post-deployment window.
The purpose of this prospective, double-blind, repeated measures study is to assess the efficacy of Binaural Beat Technology (BBT- a sound technology that uses special tones [embedded in music] through stereo headphones to affect your brainwaves in order to put you in a more relaxed state) on anxiety and anxiety related cardiovascular measures as well as to assess the feasibility of implementing a BBT intervention in a military population during the high risk post-deployment window.
A sample of 74 Warriors who have deployed will be randomly placed into two groups (music with BBT and music without BBT). Each group will be exposed to their respective intervention for 30 minutes at bedtime, 3 times a week, for 4 weeks. Quantitative and qualitative measures will be collected as follows…
Aim 1 - To assess the feasibility of implementing a binaural beat technology intervention in a military population during the high risk post deployment window. Feasibility will be measured by assessing:
Aim 2 - To assess the impact of binaural beat technology on anxiety and relevant CV health measures. These measures included:

| Binaural Beat Technology | Other | A phenomenon when two nearly similar frequencies (between 30-1000 hertz [Hz]) are presented to each ear and the brain detects the difference between the two sounds. These two sounds are processed in the superior olivary nucleus of each hemisphere of the brain. This integration of brain hemispheres produces a frequency that in turn affects the reticular activating system which alters the electrical potentials of the thalamus and cerebral cortex changing brainwave frequency. |
| Measure | Description | Time Frame |
|---|---|---|
| C-Reactive Protein | C-reactive protein is a biomarker of the inflammatory process. | Before the intervention and again at 5 weeks |
| State-Trait Anxiety (STAI) | The STAI will be used to measure overall generalized anxiety as well as current state anxiety immediately before and after the intervention. The instrument consists of 40 4-point Likert scale statements (20 related to trait anxiety and 20 related to state anxiety). Scores range from 40 to 160 with the higher score depicting a higher level of anxiety. | Before the intervention and again at 5 weeks |
| Morning Blood Pressure/Evening Blood Pressure Decline | Using an ambulatory blood pressure (BP) monitor, BP measures will be taken every 60 minutes starting from two hours before bedtime and ending two hours after rising. Morning BP surge will be assessed by comparing the trend of the number of millimeters of mercury (mm Hg) the BP increased during the first two hours after rising. Evening BP decline will be assessed by comparing the trend of the percentage that the BP declined while sleep when compared the mean awake BP. | Before the intervention, at 2 weeks and again at 4 weeks |
| Cardiovascular Reactivity | Continuous heart rate measures will be taken during five states: 1) at baseline, 2) during the training for a cognitive challenge, 3) during the cognitive challenge, 4) during recovery, and 5) when verbally coached to relax. When analyzed via the computer, a high variability response will indicate a healthy autonomic system whereas a low variability response will indicate evidence of chronic stress exposure. | Before the intervention and again at 5 weeks |
| Post Intervention Questionnaire | The Post Intervention Questionnaire will be used to collect qualitative data (3 questions to address efficacy and 11 questions to address feasibility). This instrument will be used in conjunction with field notes during recruitment to assess: 1) retention, 2) number of refusal during recruitment, 3) number of drop outs, 4) reason for drop out, 5) reason for staying, 6) number of day the technology was used (more or less than prescribed recommendation), 7) selection of music, 8) ease of use and comfort of equipment (e.g., sleep phone, mp3 player, etc), 9) adherence to the protocol, and 10) evaluation of recruitment strategies. |
