Nurses also seem to adapt to filter out the noise which seems practical but means they can also unconsciously ignore alarms or at least require longer to respond. In airliner cockpits this also became a problem when CRTs superceded analogue instruments as the constant drone of their cooling fans masked important aural cues. It has improves with the use of cooler LCDs but even now a 737 cockpit is shockingly noisy. ts
