"According to sufferers," the BBC writes, "it is as if someone has parked next to your house and left the engine running. The Hum is a mystery low frequency noise, a phenomenon that has been reported across Britain, North America and Australia in the past four decades."
Now, folks in Woodland, a little village in England's County Durham, say they're hearing The Hum. One local resident, 57-year-old Marylin Grech, tells The Telegraph that "it vibrates through the house.

If I put my fingers in my ears it stops, so I know it's not in my head."
Way back in 2004, The Guardian reported that some scientists thought The Hum might be caused by rough water that "sets the Earth's crust shaking. ... The sound is probably caused by the conversion of storm energy to oceanic waves, which interact with the shape of the ground at the bottom of the sea."
