This guy did an in depth video covering it. I believe he’s an electrical engineer. At least (as one myself) he definitely appears to have that background.
But the TLDR to your question is that the headline of this is wrong. The noise pollution is very easily measured. It’s just producing noise at extremely high levels that are not audible to the human ear. Very low frequency tones at very high amplitudes. There are several medical studies on these, I believe he cited them in the video. But, he also does his own study in the video.
It’s been awhile since I watched it. But, the idea that things are “just in people’s heads” is not really unscientific. The point is to study how seemingly “harmless” things like inaudible sounds can effect our brains and cause feelings of anxiety or doom. And constant anxiety is linked to developing real health problems (cancers in some cases). Something “just in your head” can absolutely be a real negative health outcome because the exposure is literally hurting your brain. It’s literally “just in there head”.
We all understand very quickly that a massive low frequency tone at say 80 Hz would be absolutely unbearable if we had to live near it. But, drop that frequency down to 10 Hz and now we don’t “hear” it. But that doesn’t mean it’s not having negative effects on us. And very much conclusively, from the evidence, it is.
My favorite was the 7Hz that a factory creating that just happened to be the resonant frequency of a chickens skull and was causing them to die at a nearby chicken farm.

Damn. I’m now imagining the Tacoma Narrows bridge but with a chickens head.
