Interesting.

I have a big compressor, but my wife made me take it out of the garage because it was really noisy. It's in storage. I have a few air tools, from the days when I thought I wanted to learn to paint cars. More recently, all the power tool makers have come out with alternatives to air tools. I have an electric impact wrench, for instance. When I was young there were no electric impact wrenches, or at least I never saw one.

The high speed air turbine is still my default dental drill (handpiece, we call it), but they have good electrics on that too now, which some people prefer.

The Amish use windmills to compress air, which is kinda cool.


Agreed. 

And that sound of that high speed dental drill is something no person who has ever been to the dentist can ever forget!  ;D

I've often wondered why compressors are so noisy. Sure, the physics involves all the vibration frequencies that are blasted in every direction from air that don't wanna be compressed, so to speak, but there is a sneaky way to get around that. I know they use that with mufflers. As you know, if you can get two sound wave frequencies to interlace a certain way, they cancel each other out. If they can do it with car mufflers, why not with compressors? If you put your thinking cap on, I'll bet you can make your noisy compressor purr like a kitty so your wife won't ban you from using it.
 

HEY! This guy already posted the MUFFLER sound wave interference pattern solution!  ;D

Here I show you a mod to make your air compressor a few decibels quieter. I reduced the noise by 4 decibels. What's left is mostly valve noise, and that noise can only be reduced by putting a wall between me and the compressor. This technique will work for any compressor, such as Eaton, Polar Air, Ingersoll Rand, Campbell Hausfeld, Quincy, etc. This technique will not affect your cfm.

if it has not works, is dead, being alone.
