A low hum in USA, Florida
A low-frequency hum that I perceive occasionally when it is quiet, typically while in bed, before and after sleeping. Thank you for providing this data collection facility. While I consider the Hum a mild distraction, I am extremely curious to learn of its potential sources. It would be fun to discover that the Hum-sensitive have their own "super-power". ;-)

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.
