In safety industries, particularly aviation, "alarm fatigue" is a really big deal. You recognize that pilots have limited situational bandwidth, and you REALLY don't want to be bugging them about things you can avoid. I worked in collision avoidance systems (TAS/TCASI/TCASII), and spent nearly a whole year just working on figuring out when and how we could avoid warning pilots in cases where "we're not sure exactly what is going on, so tell the pilot just in case" could potentially annoy pilots in cases like take off and landing (where they have important OTHER things to be doing!)
It's a fun balance between "possibly don't warn the pilot about something they should know about", and "don't warn them if they are busy doing something important".

More devices should have a "squelch" switch!
