Depends on a number of things like how much air pressure, how big the hole is, shape of the hole etc. I would say generally quieter than pulling the valve core.

Depending on the tire pressure? If it's above 30, it's going to be loud enough to be heard if someone is within a hundred feet. If they're inside a building, you'd probably be mistaken for something else going on in the building. A knife into a 40 PSI tire is enough to make your ears ring for a second or two.

I think the SUVs they'd be using are going to be somewhere in the realm of 35-50. Tahoes were around 38-40 when I drove one.
