I have used pomodoro timers that have a sound (for instance a clock ticking) and that's a useful way to be reminded. Unfortunately the ones I've seen to date have a reasonably limited range of sound configuration options, generally a one second tick. I would prefer to hear a quiet sound every thirty seconds, I'd also be interested in the option of a voice announcing, say, every five minutes elapsed.

The European Agency Aviation Safety Agency [2] instruction describes the characteristics of the incident but not the date.
