The article writer is an idiot and you may be too. It says nothing about DEI expertise.

This is equivalent to dunking on scientists when a flat earther claims to be a “science expert”.

I agree. So if people are hearing it and demonstrating it with decibel readers then there’s probably little to no sound dampening.

It could be but also datacenters are ridiculously loud and the sound is very high pitched. Would drive anyone nuts if they could hear it.
