I'm a 2% yaaaaaay
Also, I thought I was the only one who could hear it, and described it to my mum, and she said "yeah same", so immediately I didn't feel crazy any more. Sometimes late at night when we were saying goodnight we would also add, "the hum's being annoyingly loud tonight lol"
Whenever I had to travel out of town or when I moved out, I always THOUGHT I was going to try to listen for the hum in each new location to gather data but I ALWAYS FORGOT. EVERY TIME. Even days later when I'd come back home and hear it again, and think "next time i'm out, i'll listen" .....anyway, if people everywhere are hearing it, even in the states, it's probably nothing to do with my initial thought that it was the rumble of the sea that you just have to put up with when you live in a little seaside town.
Anyway.
I'm glad somebody made a video about this, just in case "hum hearers" don't have anyone else around them who hear it.
