That's just a normal high frequency standing wave. You're moving your head in and out of the nodes (where the waves destructively interfere).

This happened to me too when I lived in a house near to local boiling station. Once the same truck parked with its engine on near the station (service or supply, maybe), my room had many points where you can easily get panic or stress attacks. It was probably focused infrasound, not high-pitch, but few hours after, especially in sleep, I began to feel it even without that truck. Self-deception is very inductive thing.

I think that the article describes the aftereffects of something like geological activity, so while its roots are real, the consequences are the product of "tired" minds. I heard also that if doctors allow their clients to speak about symptoms in waiting room, then many of them start having these "group symptoms" and diagnostics may go very wrong way.

what's a boiling station? google isn't helping me.

I'm not native speaker, sorry. It is a building where city water is heated and piped further into nearby houses. Heat loss may be high in cold areas afaik (due to old/bad city pipe isolation), so water is heated near living blocks instead.

Interesting, thanks! In the U.S., I don't think we have hot water delivery at all, water comes to your buildings cold and is heated individually by water heaters in the buildings where it will be used. Although now I wonder what keeps our delivery pipes from freezing in the winter; maybe it just doesn't get cold enough here for them to, when the pipes are underground.

Called a "boiler house" (in New Zealand).

Is it possible to measure and map those places with affordable equipment?

It seems what happens here with your fridge is only a sign of acoustic resonance

that's due to interference and resonance of plain old soundwaves, I guess.
