Further research is warranted to explore the effects on anxiety using a larger, randomized and controlled trial. There was a decrease in trait anxiety (p = 0.004), an increase in quality of life (p = 0.03), and a decrease in insulin-like growth factor-1 (p = 0.01) and dopamine (p = 0.02) observed between pre- and postintervention measurements.īinaural beat technology may exhibit positive effect on self-reported psychologic measures, especially anxiety. Simply put, binaural beats activate the necessary brain state for you to have sharp focus and attention. PHYSIOLOGICAL: Cortisol, dehydroepiandrosterone, melatonin, insulin-like growth factor-1, serotonin, dopamine, epinephrine, norepinephrine, weight, blood pressure, high sensitivity C-reactive protein. What the Different Brain Waves Do Experiencing the power of binaural beats can be an exciting affair, especially when you understand how they impact your brain. PSYCHOLOGIC: Depression (Beck Depression Inventory-2), anxiety (State-Trait Anxiety Inventory), mood (Profile of Mood States), absorption (Tellegen Absorption Scale) and quality of Life (World Health Organization-Quality of Life Inventory). Psychologic and physiological data were collected before and after a 60-day intervention. Participants listened to a CD with delta (0-4 Hz) binaural beat frequencies daily for 60 days. The objectives of this pilot study were to gather preliminary data on psychologic and physiologic effects of 60 days daily use of BBT for hypothesis generation and to assess compliance, feasibility, and safety for future studies.Įight healthy adults participated in the study. Listeners to binaural beat "hear" a beat at a frequency equal to the difference between the frequencies of the applied tones. Binaural beats are auditory brainstem responses that originate in the superior olivary nucleus as a result of different frequency auditory stimuli provided to each ear. Producers suggest benefit from regular listening to binaural beats including reduced stress and anxiety, and increased focus, concentration, motivation, confidence, and depth in meditation. Binaural beat technology (BBT) products are sold internationally as personal development and health improvement tools.
