Alright… I wasted a half an hour of my life, so no one else needs to. The maker of the video didn’t even bother with a description. 

The title doesn’t say how they are doing this (what causes the effect and what the effect—if any—does to those affected by the “acoustic weapon”) nor who/what it effects: “Datacenters Behaving Like Acoustic Weapons - Benn Jordan”

My synopsis for you: The thesis of the video is that data centers produce infrasound (low-frequency noise) that is harmful to people who live nearby. The video shows the noise being recorded to prove it is happening.

I’m not at expert in this, so I can’t tell whether the level recorded has any effects for people living nearby as is claimed. I suppose if you need a reason to watch it, you could see for yourself if the argument and evidence seems convincing, or if you can find a flaw in it better than I can.
