Effect of Binaural Beats on Anxiety and Tolerance in Patients Undergoing Upper Gastrointestinal Endoscopy Without Sedation: A Randomized Controlled Trial

Binaural beats, or the perceptual auditory illusions created when simultaneously presenting two similar frequencies to each ear separately, have been used to reduce anxiety in various procedures. Unfortunately, no prior study involved preprocedure binaural music exposure among patients undergoing upper gastrointestinal endoscopy, and this study sought to investigate its effect on anxiety and tolerance among participants undergoing sedation-free upper gastrointestinal endoscopy.
