Also, multiple studies have shown that listening to binaural beats is associated with reduced preoperative anxiety in surgical patients 20, 21, 22, 23.
Also if you are a patient of epilepsy, you must consult your doctor before resorting to such therapy. The binaural beat frequency is equal to the difference between the frequencies applied to each ear. In a small study of 15 people, those who listened to binaural beats in the theta frequency range (3-8 Hz) for 30-minutes had reduced symptoms of mild anxiety 18, 19. Loud sounds at or above 85 decibels can lead to loss of hearing in the long run. Side effects of listening to binaural beats While there are no possible dangers of listening to binaural beats, you must make sure that the tone level you're listening to is not too high. Gamma pattern - Binaural beats in the gamma pattern are at a frequency of 30–50 Hz, helping in maintaining the feeling of arousal while awake. Thetha pattern - Theta pattern triggers binaural beats at a frequency of 4–7 Hz, followed by improved meditation, creativity, and sleep. Delta pattern - Binaural beats in the delta pattern form at a frequency of 0.5–4 Hz, inducing faster rate of sleep. This improves mental concentration and attentiveness. Beta pattern - Binaural beats in the beta pattern are at a frequency of 13–30 Hz. What makes binaural beats interesting is their ability to synchronize, or entrain, your brain’s electrical response to adhere to a certain rhythm. Alpha pattern - Alpha pattern supports binaural beats at a frequency of 7–13 Hz, promoting relaxation. That said, there are different sound wave patterns that help facilitate binaural beats. How do binaural beats work and impact the brain? As per a study published in 2015, in order to detect the binaural beat, the frequency of the tones should be lower than 1,000 hertz (Hz).
