A low hum in USA, Stevenson
Like the engine of a bulldozer on a distant construction site I live in an isolated area near a hydro electric dam with high tension wires. The dam is no longer in high capacity use. I've been here since the early 1960's and this noise was never here before. Recently they installed a service station and a small strip mall about half mile down the road that increased traffic in the area, but this is not the noise of traffic. I can hear that sound over this hum. I've rode down the street and sat under the high tension wires and the gas station and couldn't hear this hum there - only inside the house. I just wish it would stop.

Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
