It'll have to be played as "chords" ie a choice of 2-5 "notes" (sounds) played more or less at the same time, from a very extensive list of possibles, where the number of sounds, order of sounds starting, and specific sounds used for the "chord" are all random.
That would be the only way of ensuring the listener doesn't recognise any given "note" as distinct, nor any sequence repeating.
So you might need - say:
100 different scraps of muffled German conversation
100 different clinks, clanks and other machinery noises
50 of pots and pans in the galley
50 examples of laughter
50 similar but different torpedo loading sounds
and so on, so that the chances of hearing the same "chord" of notes repeated is vanishingly low. Unfortunately the human brain is very quick to recognise such repeats. Which is probably why I shall murder the Radio Officer if he plays "Tipperary" again! It may be a long way, but it's not nearly far enough!
