Some good stuff on YouTube like this guy.
I might do it but in my price range I figured it would cost at least three hundred or so to do it right so I bumped up my budget to get a polar air one that is supposed to be really quiet

That is a legit compressor closet. And setup.
I was about to do the same, but I realized the best way to eliminate sound is just to put the dang thing outside and hardpipe it through the wall.
One of my friends let me borrow his Makita compressor. That thing was quieeeet. No ear pro needed when sitting right next to it.

What compressor? What is the dB level now?
I just have a small harbor freight one now, but I will be upgrading when I redo the garage to a 60 gallon. Most likely a HF or northern tool unit. Using a compressor closet will impact the layout of the garage though and where I run the electric supply.

I have a small HF job--$39 pancake. It is so loud I can't stand it. It is louder than the old CH iron job I have. It's loud AND slow.

I'd rather spend money on a unit with a low RPM pump, then time and money to build a closet. Something to think about.
Mine runs at 72 dB:
Not that loud at all.

Well hell i didn't realize you were here. Great job on your videos. Long enough to explain but short enough to get it done. Ya'll should punch up his youtube channel if you haven't already.

I have a few pics of my compressor closet at the bottom of my thread. Very similar to YouTube video posted.

I'm shocked that guy on YouTube framed that closet into his walls. Free standing or at least double-stud would have been much quieter.

Eggcrate padding or similar on the walls would absorb a substantial amount of sound. Hard smooth walls reflect sound, soft walls absorb it.
You can definitely do things to deal with the noise that are less radical than a closet or putting the thing outside. A big place to start is the air intake. Like a car muffler, the intake can make a big difference. With my belt drive Campbell Hausfeld based compressor I see a nearly 9 db drop between straight into the head vs air filter housing + a rubber hose. My CAT compressor gains a similar change when the filter housing and rubber hose (the stock intake setup) were removed. This isn't as good as a closet but it doesn't take as much space either. If you improve the intake then add a few noise abatement panels on the walls around the compressor you might find it good enough to skip the closet etc.
One of the main reasons I am considering this in addition to the noise reduction is to provide a clean edge to run along the edge of my workbench to prevent things from falling off the edge and behind the compressor and also give it a cleaner look. I was planning on making the enclosure just wide and deep enough to get the compressor in and out if needed.
But now you have me thinking of trying to make the compressor as quiet as possible by using many of these ideas. I wonder what the result would be in building a closet and running a muffler to the outside instead of an airspace below the access door and a fan/vent to the outside for exhaust. I will also try and find a compressor that is reasonable quiet too.

I built an insulated corner closet for a 5 hp 80 gallon compressor. Stub walls are about 2’, with a 36” outward opening door at 45 degrees. The ceiling is a little lower than normal, and there is a small closet overhead with separate access for storage. Garage ceiling is around 13+’.
I built it for noise control but the “mezzanine “ is handy, and the small room is handy for storing an assortment of things.
I left a clearance of a couple inches under the door for a fresh air supply.

If you're looking for ideas for a small enclosure, FWW magazine had plans for a Shop-Vac cabinet which could probably be modified to work as an air compressor cabinet.

I built a sound closet for my dust collector and ended up putting the whole house vacuum system in there too. It has an outside window and vents the dust steam out the window after the cleaning bags. Much quieter in the shop and must cleaner also. Didn't have room to include the air compressor and it was not noisy enough to need hearing protection like the dust collector and vacuum is.

I thought about building a shroud of sorts that would hang from the wall and cover the compressor portion of my standing 80 gal Craftsman compressor. I just measured it and it's 97 decibels. I usually leave the area when I charge it up.

The challenge with enclosures or adding deadening material to the compressor itself is heat - the compressor generates a lot of it. Have to consider the worst case conditions when the compressor duty cycle is at its max.
That said, making the compressor 'quiet' has been on my list of things to do for a while...

Heat is a big deal. If you do a closet you need to setup a fan or some other type of ventilation (vents at top and bottom to induce air flow, a duct off the flywheel fan etc).
I would certainly start with a muffler upgrade. Some of the 60 gallon, 3hp models have just a block of foam right in the head.

Units like that could really benefit from even a basic muffler setup. Something like this
https://www.amazon.com/dp/B00792G8PS/?tag=atomicindus08-20 (not endorsing this one, just that it has a snorkel on it) + about 2' of rubber hose off the snorkel can make a big difference. As I said, a similar setup on my 120V belt drive unit results in a 9db drop vs no filter at all.
Next you can look at things like putting vibration damping material around the tank. If you have a heavy mat this is something you could try for free. A harder job would be mounting the compressor and motor on a vibration isolated mount. If you look at the CAT compressors they have a unibody pump-motor but that lets them mount it with rubber grommets. Again, keeping vibration out of the tank.
Of course, moving the compressor out of the room is generally going to be the best.
