A low hum in USA, Dayton
A lower hum that does increase in volume at times. It stays at a steady pace but, at times can change to a different pattern of wave. It will then go back to the original. It's like a "voooohm voohm" hum sound that I have decscibed to my husband like a echo hum( visual to put it- like a ripple affect from when a rock is thrown into water) Description of the sound is the best compared to the generator(couldn't get the exact match)

The sound is best descibed as deep vibration or low hum that sounds like it is from an engine or truck, but the sound seems to be travelling through a medium as a vibration. Sometimes it fl…
the accounts read alike, found by meaning rather than by shared details
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.
