The Mysterious Hum | Thunderblog
You hear a low rumble that sounds like it is about a mile away. You go outside, but the annoying noise is actually louder in your house. The low hum is not an appliance, and there are no factories or highways nearby. You and a few other people in your community can hear it, but not everyone. Your spouse can’t even hear it. Are you crazy? What could it be? You can swear the odd sound is real, but you are afraid to say something.

You are not alone. For decades, many have heard this noise, called The Hum. It is usually described as a low rumble, like an external diesel-powered machine in the distance.  Conversely, many hear the low murmur internally. The steady drone is not just an irritant for people but affects their daily functioning. The Hum can be hazardous, often creating distress and contributing to a loss of sleep. The danger level ranges from a minor irritant all the way to suicide.
