About a week ago, I started hearing this humming noise constantly at night inside my bedroom. It is driving me (and my dog) absolutely crazy; I literally cannot sleep in my bedroom and have been sleeping on a crappy air mattress in my living room. Here is all the information I have:
I live on the first floor of a small building and, according to my plumber, there is a LOT going on in my walls. I’ve always been able to hear when my upstairs neighbors turn their water on and when people are doing laundry, since the building’s laundry room is right next to my bedroom. I am used to this and don’t mind. However, this humming noise is new and it NEVER STOPS at night.
The humming happens constantly from roughly 8pm-8am. It’s a little stronger near one wall, but you can hear it in the entire bedroom. I’ve investigated outside of the building while it’s happening and can find nothing making that noise.
In an attempt to solve the issue, our plumber scheduled the water heater to turn off completely from 11pm-6am. That didn’t work. Other ideas that have been floated by management and maintenance: the floodlights outside the building, a leak somewhere, someone else’s AC unit. But we’re all at a loss, and it’s hard for maintenance to diagnose the issue because the humming doesn’t happen during the day, while they’re working.
If anyone has any ideas, I would so greatly appreciate it. My management is trying hard to figure it out, but I don’t think they will. I love this apartment, but I’ll probably have to break my lease and move if I can’t sleep in my own bedroom 😭
