Just a few weeks ago, the Times had another interesting article about how a Bronx hospital has tried to address this problem through a "Silent Hospitals Help Healing" program:
The reality of noise and interruption is a major part of the patient experience, and, thus, something chaplains need to be aware of.
Pieces of equipment like medication carts with squeaky wheels have been repaired, and sound-absorbing ceiling tiles and curtains have been installed.
Workers are encouraged to wear softer-soled shoes and to keep hallway conversations to a minimum. The volume on intercoms has been turned down, and beepers have been turned to vibrate mode. Patients now have the option to wear headphones while watching television.
