Active Control
Participants assigned to this arm will listen to a 30-minute binaural beats audio session at a comfortable volume through standardized over-ear headphones while in the post-anesthesia care unit (PACU). The audio will use a primary target frequency of 10 Hz (alpha range), created using soft sine-wave carriers in the 200-600 Hz range that generate a 10 Hz interaural difference (e.g., 400 Hz left ear / 410 Hz right ear). Volume will be set at a comfortable conversational level (\~55-65 dBA) and may be adjusted by the participant. The session will begin within 15 minutes of PACU arrival. Participants may stop the audio at any time.
Participants in this arm will receive usual postoperative care in the post-anesthesia care unit (PACU) and may listen to music of their choice using standardized headphones. They will select their preferred music and listen for 30 minutes at a comfortable volume (\~55-65 dBA), which they may adjust as needed. No binaural beat frequencies will be used. Music listening is optional and may be stopped at any time.
