What your vac is sitting on is usually the biggest noise contributors in my experience. Try placing it on something like a mouse pad on a solid surface and see if that lowers the noise.
I had mine on a bar stool that rattled like no tomorrow. Now it's on a few bricks with a mouse pad and it's much more quiet

the vac on wood floors vibrates the shit out of the ground and walls. i try and prop it on something with dampening..
i like the exhaust hose! i tend to just wrap my exhaust up in rag.. i can push my vac to about temps of 160F before it over heats :]
i keep it around 130 running..

You can cut the noise in half by adding a mist oil filter if your pump support's it, I've seen dude's adapt oil filters from cars when they can't get one.
Also another major noise is actualy it vibrating other objects. I keep my pump on a quarter inch rubber gasket mat with a cutting board on top with blue foam on top of that, then that egg carton style sound canceling foam. The pump is about 60 pounds so it pandcakes all that into 3 inches of anti vibration, after that you just gotta let the wife know to deal with it, mine has learned to sleep all night while i start n stop the pump on the other side of the wall.

Maybe this will give you some ideas for vibration.

Hey there's one advantage to using a mityvac hand brake bleeder to purge...it's totally silent. Since I do much of my oil work (and consumption) after midnight while people are sleeping its great. I'm saving up for a full size vac pump & chamber but the mityvac will purge BHO to clear shatter...that is all I need for now

I saw the video on youtube of a guy using car oil filter to make a ghetto filter for vacuum pump. I don't agree in his evaluation of the efficacy on his homemade contraption, it is only shielding the area from oil splattering out, but doing barely anything to actually filter the mist. I know because I bought the filter he recommended in his video and made the thing myself. Almost the same amount of vac oil mist was generated as without the contraption. For me the DIY filter did not do much to reduce noise either, I don't know if a real filter will do much.
I run a noisy refrigerant recovery pump and what I did was build a silencing box around it consisting of 4 layers. Inner layer has mass-loaded vinyl, then a layer of 1/2" particle board, then a layer of acoustic caulk, then another 1/2" particle board over. The box has ventilation holes where appropriate, and where the holes are, I placed a baffle consisting of two 1/2" particle board with acoustic caulk sandwiched between. It makes a big difference in sound. Now the sound is dampened to less than a household vacuum cleaner.
Btw if conservation of water is not an issue, consider looking at a faucet aspirator to pull vacuum.

Hehe I built it too and it was a piece of adapter after adapter shit cuzz the thread's don't match the shit on my fischer, 3 days later the $150 oil mist filter that's proper for the pump came in the mail. That i know reduces mist completly and does it's part in noise reduction. If it's a super issue you gotta start fucking with egg carton's unless you have mountains of sound booth foam you stole from work years ago.
Thumbs up for water aspirator's, if you got a coil chiller or some other contraption for cooling you can run aspirator's perpetually with a jet pump. Your really cooling the jet pump in that situation, but if you got the water pressure and your not draining the county drinking water it's cheap as hell to get in the game.
