Binaural beats in the lower beta frequencies (14 to 30 Hz) have been linked to increased concentration and alertness, problem-solving, and improved memory.Binaural beats in the alpha frequencies (8 to 13 Hz) are thought to encourage relaxation, promote positivity, and decrease anxiety.Binaural beats in the theta (4 to 8 Hz) range are linked to REM sleep, reduced anxiety, relaxation, as well as meditative and creative states.Binaural beats in the delta (1 to 4 Hz) range have been associated with deep sleep and relaxation.You can also decide which brain wave fits your desired state. You can easily find audio files of binaural beats online, such as on YouTube or via downloaded audio files to your mp3 player or mobile device.Īs mentioned earlier, for a binaural beat to work, the two tones have to have frequencies of less than 1000 Hz, and the difference between the two tones can’t be more than 30 Hz. The use of binaural beats in this way is sometimes called brain wave entrainment technology.Īll you need to experiment with binaural beats is a binaural beat audio and a pair of headphones or earbuds. The theory is that binaural beats can help create the frequency needed for your brain to create the same waves commonly experienced during a meditation practice. When you listen to a sound with a certain frequency, your brain waves will synchronize with that frequency. Practicing meditation regularly can be quite difficult, so people have looked to technology for help.īinaural beats between 1 and 30 Hz are alleged to create the same brain wave pattern that one would experience during meditation. Meditation is the practice of calming the mind and tuning down the number of random thoughts that pass through it.Ī regular meditation practice has been shown to reduce stress and anxiety, slow down the rate of brain aging and memory loss, promote mental health, and lengthen attention span. Further research is warranted to explore the effects on anxiety using a larger, randomized and controlled trial.What health benefits are binaural beats claimed to have?īinaural beats are claimed to induce the same mental state associated with a meditation practice, but much more quickly. 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. PHYSIOLOGICAL: Cortisol, dehydroepiandrosterone, melatonin, insulin-like growth factor-1, serotonin, dopamine, epinephrine, norepinephrine, weight, blood pressure, high sensitivity C-reactive protein. 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.
