Very low pitch vibrational rumbling. Like a distant train passing or large truck idling outside. Sometimes I can feel a vibration when the sound is the loudest. It seems as if the hum is coming from the ground. If I put my ear against the wall of my house, it is louder, as if the house is a conductor. I can also hear the hum while sitting in my car in the middle of a forest, far away from any civilization. Most people can hear it if I point it out to them.

Has this happened to you?
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.
Nothing is tracked back to you and nothing is sent on your behalf. The link is just the page you are reading.
