In terms of an example, say you had 1,000 tiny speakers. Could you
some how arrange those and control them with a computer so that they
"add up" to create the sound of one large speaker? Could you somehow
approximate a very low note from a combination of speakers that
individually can only produce high notes? See where I'm going with
this?
Two sine waves that are at just slightly different frequencies will
produce "beats" at a much lower frequency. Those beats can sometimes
sound like a lower frequency note.
I'm not quite sure what you are getting at, but here's something that
might interest you. Those beats can be heard even when they are
produced by notes that themselves are too high to be heard. So that if
you very carefully controlled the output of numerous high frequency
speakers, you could produce sound which would give a human the
impression that he is listening to sounds (even music or speech, for
example) at much lower frequencies than are actually being produced.
