I can't recall where I saw it, there's at least one company working on this issue specifically for nursing staff. Everything beeps in hospitals, but there's no rhyme or reason to it, so room call responses are delayed, serious alarms can be missed, etc.

IIRC, the company's idea is to create a harmonious sound bed when everything's fine, and make different kinds of "out of the norm" alerts use a variety of sounds so that nursing staff get more info about what's wrong before finding the thing thats sounding an alert and looking at its screen.

This company's goal is to ... change an aspect of hundreds of different million-dollar highly regulated machines made by dozens of different multi-billion-dollar worldwide companies? And somehow make money doing this? Good luck, I guess.
