I understand. Perhaps the patients just need ear plugs. ;-)
After being in the hospital a few times, I brought ear plugs on my recent stay. Then the nurses wonder why you aren't waking up and get right in your face. A pillow from home is also a must. After being on a breathing tube, chapstick is worth its weight in gold.
I had a nurse do a follow up call after I got home and she said the hospital isn't where you get well, home is where you get well. The hospital is for treatments and monitoring.
