I know it sounds crazy, but my refrigerator beam some whistle alike sounds. If I move my head like one foot beside I don't hear the sound, but one foot on the other side and I hear the whistle.
Edit: I have a video of it, it's not as clear in the video as it is in real life though. You have to put volume at 100%.(https://www.dropbox.com/s/7h7n46kzqarzt0l/fridge.mp4?dl=0 https://www.dropbox.com/s/7h7n46kzqarzt0l/fridge.mp4?dl=0)
- IshKebab 9y agoThat's just a normal high frequency standing wave. You're moving your head in and out of the nodes (where the waves destructively interfere).
- wruza 9y agoThis 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.
- mynewtb 9y agoIs it possible to measure and map those places with affordable equipment?
- jrochkind1 9y agowhat's a boiling station? google isn't helping me.
- wruza 9y agoI'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. Like this one (hot link): https://i.sakh.com/info/p/photos/13/131076/f58f5390937072.jpg https://i.sakh.com/info/p/photos/13/131076/f58f5390937072.jp...
- jrochkind1 9y agoInteresting, 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.

- olivierkaisin 9y agoIt seems what happens here with your fridge is only a sign of acoustic resonance
- posterboy 9y agothat's due to interference and resonance of plain old soundwaves, I guess.
