Here's another sound reducing method. This is  the old "Dissimilar Materials" sound proofing technique with many applications. He also forces the sound to make two 90 degree turns. This quiets the compressor down much more. I suspect he is creating a partial sound destrucitve interference pattern with these forced turns.

For plans, click "Show More" below. --- Make your generator or air compressor 5x quieter using a box  that can be disassembled and stored.  I also show the exhaust system that prevents carbon monoxide poisoning.   I show a video of my 3500 watt  generator running alone, and while it continues to run I assemble a quiet box that I built, around it. The video shows the audio waveform of the generator's sound decreasing as the box is assembled, and my video editor's "db full scale" meter is also shown in real-time. Finally I show the generator running alone and compare it to the generator running in the quiet box in 3 second bursts to allow you to hear the before and after difference.

I also show the exhaust system that vents the generator's exhaust high up above the roof to insure that carbon monoxide will not get into the house no matter which direction the wind blows.  Because of this, the generator can be run in our carport out of the rain.  An additional benefit is that the exhaust system helps with quieting the generator without adding a secondary muffler, by routing the "exhaust sound" above the roof.  Two benefits for the price of one.

Finally I show how the panels of the disassembled quiet box can be arranged for storage in the bottom of a small clothes closet -or- in a small footprint configuration for storage in an even smaller footprint space.

UPDATE:
I was not planning to do this but because of requests to buy plans for my quiet box, I put a package together that consists of plans and step-by-step instructions for building my quiet box and both sound baffles. Also included are a video, plans for 2 larger size quiet boxes, and the Sketchup files for my quiet box and baffles.  If interested with no obligation to purchase, send a request for details to usefulgizmos@gmail.com. If not interested, please just ignore this update.  Thank you.
