Low strong rumbling usually at night. Sometimes accompanied with vibrations that can be felt. Sounds amplify while inside. It's difficult to determine what direction they come from. At times I've considered if they come from under ground as if someone were tunneling under my house. It's a lower frequency than the noise of semi truck tires traveling down a highway that you may hear miles away. Similar to that if a military helicopter without the chopping sound and whine of the motor. At times I have thought it was the farmers and their machines that they would run at night. I have also caught military helicopters in the area at times that seem to contribute to the noise. Sometimes semi trucks driving down the high way the tires can produce a low hum from miles away that grows and changes pitch as they approach and pass. Doing any activity would drown out the noise. Being inside seems to amplify the intensity
