Go to a modern hospital emergency room, it's a cacophony of devices all vying for attention. I walked down the hallway and realized every room in the place had a different audible alarm—all active! I suspected the device manufacturers were all worried about liability for their device, making sure to notify that a patient had a problem. The end result for the medical staff was an endless chaos of noise. Complete systemic failure of UX from a practical standpoint.
