Adjacent, I work in a lab so we have dozens of ovens and freezers running constantly, so I'm intimately familiar with the constant hum, even though my office is a couple of doors away from the oven room.

We had a full site shutdown last week, which involved all power being shut off, which meant no running ovens.

The lack of sound felt so strange, like I was somewhere I shouldn't be, or in some sort of liminal space. It was unsettling in the silliest way.
