There’s a steam plant for my local hospital about 300m from my house. When I’m in my basement trying to record drums, I can audibly hear when the plant is running. Super low, sub-50hz hum. It gets into all my mics.
Fortunately my bedroom is on the second floor of the house so the resonance doesn’t keep me up at night.
Pipelines also cause a resonance hum that some people CAN hear for miles, and it drives them batshit.
Spend time at an interstate rest stop. The vibration can be intense.
