Treatments
Experimental: Binaural Beats (BB)
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.
Active_comparator: Music of Choice (MOC)
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.
