Summary
This study tested whether playing recordings of familiar voices or nature sounds could improve consciousness, reduce pain, and stabilize vital signs in 90 critically ill comatose ICU patients. Patients listened to the sounds for 15 minutes twice a day over a week. The goal is to find a simple, non-drug way to support awakening and comfort in the intensive care unit.
