A low hum in USA, Inver Grove Heights
It's a constant hum with a vibration. Sounds like a massive deisel engine idling down the street. I've heard this hum for over twenty-five years but the reason I'm reaching out now is because something has changed and it's becoming harder to ignore as it's affecting my health. I wake up in the middle of the night and my whole body is vibrating to it. I've taken to sleeping on my couch because there's more ambient noise to help mask it.
