After ten years, my team and our audio algorithms can decipher many colony
sounds - that are far more diverse and complex than the examples of the
experienced beekeeper who can 'hear' a queenless colony, Eddie Woods who
could hear colonies about to swarm, or Arnia's scale hives plus a couple of
new companies who use overall colony noise to judge colony vigor).   I
wouldn't be surprised if the bees use sound to communicate colony status.

Professor Bromenshenk,

Nice to hear how much you are fond of bee sound because I am too.
I wonder whether you use autocorrelation of bee sound together with the
power acoustic spectrum?

The most detailed about using power spectrum in beekeeping research, I've
found pretty ago, in one small Russian book, it was on 4 pages explained.
But they didn't mention autocorrelation in that time. Later, maybe about
10-12 years ago (or longer, can't remember), there were two articles in
Russian beekeeping journal "Pcelovodstvo", written by one beekeeper who
experimented with using autocorrelation of the bee sound and got very good
results.
