If a million tiny robots shouted at once...

... aat the exact same nanosecond, could the sound accumulate and be audible in the same way as it would if it were just one large robot?

different origin points and sound travel time, so no

Depends. If they're all in a circle, it would cancel each other out, effectively producing no sound

They would need to time it a little bit off from each other to it better syncs up, but regardless of the timing within x time frame you should be able to hear it.

That only happens with inverted waveforms.

You mean to account for the disparity of physical location in relation to the listener?

Ok, to update the question then:
What would the sound of 1 million tiny robots shouting 'Hello' at once be like, using say the smallest full-range speakers currently available?
Or what would it be if they each played an middle C on flute, if that's more interesting to consider?

And to the original, if you did have each robot apply a delay in order to target a physical location for a synchronised sound... would they then be able to replicate a single emission from a larger robot?

it depends on the exact size of the robots, but if you sync up the robots with nanosecond precision you could do some crazy shit. You only specified that the sound needs to be audible. With a bunch of tiny cooperating robots you can do acoustic beam forming. Hell you might even be able to do acoustic holography. With beamforming, a human listening probably wouldn't be able to tell the difference.

>>speakers
we don't need speakers. The robots can just wave their arms or legs around real fast, which they should be able to do because they are small.
>>middle C on a flute
if said flute is tiny it will produce tones on the ultrasonic range.
