Default Re: Air compressor alternatives

I built a box for my California Air Tools. It made a tremendous difference.

I bought a low price ($20) sound level meter just to see how the box worked. The meter claimed to be calibrated but I have no way of checking.

My outside shop compressor, the loud kind, measured as putting out 92 dBA of sound.
The California Air Tools compressor put out 70 to 75 dBA of noise. This is inside next to my engraving setup. Without the compressor running the sound level in the room is 45 dBA.
After I put the compressor into a box I built, the sound was at 50 dBA.

I found many designs on the internet for boxes. I made mine with gypsum drywall material and 2x2s for the frame.
