Researchers from the National College of Natural Medicine in Oregon conducted a study on binaural beat therapy in 2007. However, the researchers noted that people experiencing high levels of preoperative anxiety could listen to binaural beats for up to 1 hour before anesthesia to reduce levels of anxiety. 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.Alpha pattern: Binaural beats in the alpha pattern are at a frequency of 7–13 Hz and may encourage relaxation. ![]() ![]() Theta patterns contribute to improved meditation, creativity, and sleep in the rapid eye movement ( REM) phase. ![]()
