A low hum in Sweden, S�dert�lje

Like distant diesel engine or a large industrial fan far away. The hum appeared very sudden, about 3 months ago. Since then I've heard it, but not everyday. Ear plugs doesn't help. Even though it really, really doesn't feel like it's from inside my head. It's really like it's from somewhere else I have searched my whole house. Turned off the electricity to identify any source. Walk around the neighborhood and listened. Even been driving around trying to find a source, without any result. In the beginning it was horrible. But now I've started to accept the sound and it doesn't bother me as much as before.
