This single-blinded, three-arm randomized controlled trial evaluated the effects of different auditory environments on laparoscopic task performance and mental workload among novice surgeons in a simulated setting. Sixty participants were randomly assigned to one of three groups: preferred music, white noise, or silent control. Participants completed standardized laparoscopic simulation tasks. The primary outcome was task completion time. Secondary outcomes included mental workload assessed using the Surgical Task Load Index (SURG-TLX), perceived stress, and heart rate variability. The study aimed to determine whether preferred music enhances technical performance while reducing cognitive workload during laparoscopic simulation.
