The participants in this study listened to 30 minutes of binaural beats before surgery. A 2005 study involving more than 100 participants who were due to receive general anesthesia for a day procedure reported a decrease in preoperative anxiety after exposure to a delta wave binaural beat. However, the authors stated that it warranted further study only as a therapeutic measure to support conventional treatments for anxiety.ĭespite this, other researchers have continued to investigate this therapy. Share on Pinterest A person may reduce anxiety before surgery by listening to binaural beats.Įarly research from 2001 suggested that binaural beat therapy may yield some benefit for people with mild anxiety. The study authors suggest that these frequencies promote maintenance of arousal while a person is awake. Gamma pattern: This frequency pattern accounts for a range of 30–50 Hz.However, it can also increase anxiety at the higher end of the range. This frequency range may help promote concentration and alertness. Beta pattern: Binaural beats in the beta pattern are at a frequency of 13–30 Hz.
Delta pattern: Binaural beats in the delta pattern operate at a frequency of 0.5–4 Hz with links to a dreamless sleep.The study authors explain that there are five different categories of frequency pattern: The findings of a 2018 study suggest that listening to binaural beats for a recommended period can affect a person’s subsequent behavior and sleep cycles. The binaural beat that a person perceives is the frequency difference between the waves entering the left and right ear.įor example, if the left ear registers a tone at 200 Hz and the right ear registers one at 210 Hz, the binaural beat is 10 Hz - the difference between the two frequencies. Share on Pinterest Binaural beats therapy may help treat anxiety, stress, and related disorders.Īccording to a 2015 literature review, the tones should be at frequencies lower than 1,000 hertz (Hz) for the brain to detect the binaural beat.
