Noise Insulation for shop compressor?

[PILOON]

An enclosure lined with old carpeting will do wonders.
Easy to wire a computer type (muffin fan) to aid cooling. (wire thru the pressure switch)
Dense rubber under the compressor feet will also help kill vibration type noises.
Lead sheeting is good for high pitched noise.
If in an enclosure, thicker denser wood will help.

The felt type under carpeting used in cars will kill lots of sound.

Never tried it, but I wonder if wrapping the tank with a felt blanket would help some.

A thought: wrapping the tank with self adhesive roofing membrane! (should kill the 'tinny' sounds.)

LOL, mine is oil based and under a counter near garage door and happens to be about 10 feet from my bedroom.
It does occasionally disturb my sleep if it kicks in during the night but I cured that by removing the one hose that occasionally leaks air slowly.

Okay I am now on the hunt for reclaimed insulating materials. May be a bit red neck but worth the experiment. My shop has been evolving for years (like many others I am sure). I do like the idea of locating it outside the interior walls. The walls and floor space is a premium in my 2+ car sized shop. Please keep the ideas coming!

I am also going to try anti-vibration pads under the compressor feet. Sitting on concrete just amplifies the noise and vibration.

I bought mine through mcmaster carr:

Sorry to be a pessimist but my guess is that it will not help much. My compressor is just dang noisy and any deadening of the feet I can't see helping. I did mount it on a homemade dolly with hard rubber castors to move it around. Can't say that did anything for sound.

OK, several people keep saying intake silencer/muffler, but nobody has pointed a link to anything that I noticed. I could use a bit of noise reduction on mine too. It isn't the worst, but mainly because it is in the front half of the shop and most of my work is in the back half where the wood shop is (with a wall in between). When I am working in the front half, I have to use muffs when it is running or it drives me bonkers. I measured it one time with my phone but forget the decibel level. I picked up a California Tools portable compressor that was said to be very quiet for finish nailers and it is great. Very easy to live with that right next to your ear even. But that is a whole different world from the big one in the shop...

So if anyone can point to a source for these mufflers (ones that actually work!), I'd appreciate it, as I'm sure would others.

Mine is a 60 gallon, 6hp and is stationary. Loud and obnoxious but not for long. 26 years of racket. Loud noises are beginning to startle me and I don't like it.

Google air compressor muffler about a gabillion choices.

If it was me though I would sell that monster and buy a quiet new one. California air tools has them in all sizes. I have a one hp version that is barely audible standing next to it.

Would like to upgrade but for a 60gal comparable unit the California Air Tool compressor is 3 times the money! Maybe I need to make that jump if I could unload my Husky brand. The advertised decibel levels are 'quiet' impressive!
