Odd Question - What is this noise in my new rental house wall?

[Erin Weiss]

This is an odd question but maybe someone can help. I just bought a new rental house and found out there is a very loud vibration noise coming from the wall. It will vibrate really loud in the house and I can't imagine my renters not complaining about it especially when sleeping in that room where it's the loudest. I want to fix the issue before I get renters in it.

It's on the back wall of the house which the electrical box and wiring also sit.

There's no pattern of buzzes but usually it will hum several times and will come and go. Here's a video.

Anyone have any ideas what this could be?

I have talked to so many contractor friends about this today.

Since you have eliminated most other suggestions we will go with an electrical issue. Since that is now the prevailing guess I reached out to 3 electricians. Got anything from a faulty surge protector at the box to a poor connection at main feeder cables an they are arching inside the box to "A short with surge somewhere at the box location".

If we do not get an answer soon Ind IN. is only twelve hours away and I have driven greater distances for a lot less "need to knows"!

Have a great day!
