Clinical Application of Listening to Music to Prevent Delirium in the Intensive Care Unit

The goal of this clinical trial is to learn if listening to music can prevent delirium in older adults admitted to the Intensive Care Unit (ICU). The main questions it aims to answer are: * Does listening to music increase the number of days participants are alive and free of delirium and coma during a 7-day period? * Is personalized music more effective than generic relaxing music? Researchers will compare Personalized Music and Relaxing Music to Standard Care (no study-provided music) to see if the music intervention improves delirium outcomes compared to usual care. Participants will: * Listen to music through headphones twice daily (morning and afternoon) for at least 30 minutes during a 7-day period (intervention groups). * Receive standard ICU care and undergo daily assessments for delirium and level of consciousness.
