Each individual human would have been relatively quiet, but because there are a lot of them (potentially hundreds), they end up being, as a whole, loud enough
This might happen because of “resonance” - but I don’t know your specific scene.

the noise of the quietest server seems to disappear whenever the loudest is running, so it kind of does blow my mind how our perception of noise works…
The effect with the servers is called “sound masking” (and some other commenters have written about it), and how our peception works here is called “auditory masking” (nobody has mentioned this one so far).
