Sentinel: Descendants in Time Hints

I can't distinguish the sounds. How many are similar?

  • 1 of 5: As mentioned earlier, it may help to use the Settings menu to turn off the music background, and/or raise the volume of the other sounds.
  • 2 of 5: At least two of the cranks generate sounds vastly different from the others.  These can be eliminated.
  • 3 of 5: Are all of the remaining four identical?
  • 4 of 5: At least three are.  But the fourth is actually just slightly different.
  • 5 of 5: Make note of the three cranks (and the associated glpyhs on their posts) that produce matching sounds.
