The binaural beat group will wear earphones and listen to binaural beats from the time they arrive at the operating room until the surgery is completed. The control group will wear identical earphones but will not receive any auditory stimulus.\n\nDuring the procedure, standard vital signs and the bispectral index (BIS) will be continuously monitored in both groups. Following the surgery, the investigators will assess the patients' overall satisfaction using a 7-point Likert scale. Secondary assessments include patient preference for the anesthesia method, intraoperative pain intensity, sedation level, anxiety level, and quality of life (EQ-VAS) measured by a visual analogue scale. Any surgery-related discomfort or adverse events will also be recorded and compared between the two groups.",[70,71,72],"Cataract","Binaural Beats","Geriatric Anesthesia","2026-05-19",{"date":75,"type":76},"2026-05-27","ACTUAL",{"date":78,"type":76},"2025-08-07",{"date":80,"type":64},"2026-07-08",{"name":5,"class":6},1]
