Exhaust sound and how to mitigate?

OK, so for inside noise (obviously without filter) with venting through the supplied hose to the outside:

This is 3’/1m in front of the unit. This is in a normal house. I chose a-weighted, because I felt like it. The room is carpeted, has a suspended ceiling with acoustic tiles (normal office tiles) and otherwise is probably just like your office.

Now in fairness this is a PRU with a not perfectly sealing lid (and I didn’t put my weight on top, since I was only cutting wood for a few seconds so it might be a smidge louder even than normal). And before @palmercr jumps on this as being non-scientific, I’m standing here in pajamas and my coffee is brewing, so that’s what I can accomplish at this hour…
