A low hum in US, Charlton
Low frequency hum, always same frequency, I'd estimate around 50hz (at least my perception). I only hear it at/in my home, if I'm at another location, I don't think I've ever heard of it. I've actually called our local law enforcement to see if anyone else is complaining about it, they state they have not received other reports. It is not so bad as to keep me up at night or to be highly annoying, but it is quite perceivable. Is not constant, sometimes it's there, sometimes not. Found your site from "Stuff you should know podcast"; hope you get to the bottom of this, it is super annoying!

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.
