Denti asks a good question. If I may "ponder out loud" on his thought ...
If the aural alert goes off during a time when the crew is close to task saturation, particularly tasks heavy with comms/hearing/talking, will an added aural input likely to be edited out, left in the background noise, or pushed to the front of the line for cues to perform an unplanned action?
Why do I say unplanned?
The fraction of a second before the aural cue goes off, the crew are doing something else, and taking other actions (some of them possibly wrong or in wrong priority) when the cue to "do something else" arrives.
If the core problem is that of getting behind the aircraft, and having to catch up, are you as likely to respond to the alert with unsuitable action as with suitable action?
Does this not point to training and proficiency?
