A low hum in UK, Exeter

Low persistent hum that I only become aware of at night I have tried turning off the electricity thinking it might be something like a fridge but that doesn�t work. I�ve been out walking around the neighbourhood in the middle of the night to see if there are any lorries parked up nearby. I know my neighbour keeps computer servers in his shed/office but it doesn�t seem to be any louder near there than at the front of the house.

There is rotation in the hum. The hum is constant with variations of something working. Before I knew this was a world wide problem, I did some investigating. We have water turbines nearby.
