Explanation:

Delirium is a serious disturbance in mental abilities that results in confused thinking and reduced awareness of the environment. The start of delirium is usually rapid — within hours or a few days.
According to a study published in the journal, American Journal of Critical Care, Music may decrease delirium. Delirium is a form of acute brain failure with no effective treatment that especially affects patients on ventilators in the intensive care unit (ICU). The study, noted that critically ill individuals who listened to slow-tempo, relaxing music with 60 to 80 beats per minute had decreased need for sedatives, fewer days of delirium, and were more awake.
