Somewhere in the shop area there’s a sound pressure (decibel) meter. It’s in a zippered hardshell case. I put it somewhere a while ago, and now I don’t remember where.
If you find it, please place it in the electronics area.
I think I saw this recently. Maybe on the hand tool cart in the wood shop? I’ll look again next time I’m in.
I also think I saw something like this recently, on the 2nd shelf down in the office/IT cabinet
