Introduction: Patients admitted to the intensive care unit who require mechanical ventilation are surrounded by an ambient noise level ranging from 60 to 90 dB, well above the 40 dB recommended by the World Health Organization (WHO). Methodology: A randomized crossover clinical trial with intubated patients who presented hypnotic levels of Bispectral Index (BIS) ≥50. The primary outcome was the level of comfort regarding the Bispectral Index, the Ramsay scale and the Behavior Pain scale (BPS). Results: 82 were randomized. In both groups, during the music therapy and sound isolation periods, an average decrease of 4.5 points in the BIS score. No residual effects were observed between sound isolation and music therapy. Conclusions: Sound isolation and music therapy slightly improve patient comfort in terms of BIS and do not alter the values of comfort present in the initial period of the study in the BPS and Ramsay scales. ​
