My office (more of a control room) is kind of loud. There are some old servers in the room and there are industrial steam pipes just above the ceiling tiles. It's ~65 db which isn't too loud, but sitting in it all day really bothers my ears with my hyperacusis so I wear hearing plugs almost all day. It's also some high frequency noise which I kind of doubt the db readings on. There are some areas I have to go into that are probably around 70-80db, I always wear hearing plugs. There is one area where I have to go into infrequently (maybe twice a month or so) that's a constant 95db of some lowish tones (not bass but think of a huge compressor in a small room). It really feels like more than 95db. I double up on the best hearing protection when going into that area and try to keep my time in there at a minimum, but I still don't like it. It's low enough and loud enough that I'm sure there's some bone conduction going on.

Do you have hyperacusis too? I would for sure double up on the best earplugs and ear muffs you can if you are running a chainsaw. I think that a gas powered chainsaw would be too loud for me even with double protection.
Like you my tinnitus gets much louder when I put earplugs in, and it doesn't seem like it's just from blocking out sound because it doesn't seem to be as bad when I put earmuffs on. If I have a lot of noise exposure that day even while protecting my hearing as much as I can my tinnitus will be louder in the evening and the next day.
Work caused my tinnitus and hyperacusis, and I completely understand wishing you could get a quieter job. I feel stuck too, but I have bills to pay.
