#2I was looking for some good notification sounds for my ESP Home's buzzer. These are a great inspiration.

#3Fascinating. Interesting to hear the differentiation in severity in the same class of error.
Though a bit disappointing that there is no machine that goes PING! [1]

#4And how about the fact that there are simply too many of them!
I was once in the recovery room with my wife. For some reason the sensor was having a very hard time reading her pulse. The normal bips would frequently fail. Too many failures in a row and the alarm would start it's EEEEEE scream we've all seen from Hollywood. It would shut up as soon as it managed to pick up a beat.
Hers was definitely not the only one in the room occasionally screaming. The nurses were completely ignoring it. Quite understandably so as it was obviously doing false alarms. But in a flood of false alarms like that are the real ones going to be noticed??

#5Trying to figure out which melody was which in an emergency doesn't seem like the most human-friendly.
Contrast with the GPWS warnings in aviation, which tells you what the problem is (TERRAIN TERRAIN) and what to do (PULL UP) in a progressively more alarmed voice as things get worse.
(Well.. Sometimes you hear of some particularly bright individuals who think the bank angle warning is a checklist item, but it's generally hard to get these wrong, compared to many other beeping warnings)

GPWS warnings should be the gold standard for any sort of urgent audio alarm.

#7What's not clear from this webpage is whether these are actually used anywhere. Are they? I couldn't tell.

They also have their share of cavalry charges and buzzers. Plus the plane sometimes calls you a retard

False positives are definitely a problem. When you read industrial accident reports one extremely common theme is some sensor that was notifying the controller of the problem, but that sensor had a history of false positives so it was disregarded. Companies that don't take false positives seriously are inherently dangerous.

At :42 I think the buzzing sound is the "stick shaker" stall warning. It literally shakes the pilot's control yoke. So not only is it an alarm, it's also reminding the pilot of the correction needed: to push the control forward.
