In the pre-surgery area. Gown is on, IV started and electrodes placed.
In this picture, patient has been taken back to the pre-op area, put into hospital gown, with IV inserted and electrodes attached, but, thanks to the beautiful, calming music is still smiling and not overly anxious about the procedure that is about to happen. Nurse has already asked at least 5-10 minutes worth of questions, but patient could easily hear, because headphones are not noise cancelling, merely muffling. When patient is in the operating room, surgeon often has his own upbeat music, which is the opposite of what the patient needs to hear and entrain with. Conversations, too, are often not what the patient needs to hear.
