I like that. It kinda makes me want to repeat my hog house kluge made from Celotex Soundstop and duct tape. It had both ends open, but I leaned some board against each end to block sound but still allow some air in and out.
If you were on this edge of the continent, we could make an event out of it. Test 'em with the same meter in the same environment. All we would need would be a bartender and a grillemeister.
Mine is lighter, though. ........No anvil.

I have tried to improve on this idea and hope it's okay with Prof'. In the picture, maybe the gen is set to far to the rear?
My present enclosure is constructed using 1x2's for framing, 30" long, 24" wide and 20" high. Using what is available at Home Depot, the black 4x8 sheet of 'QuietBoard' ~ 'SoundStop' board is coming soon. Now comes the fun. Trying to stop the heat recirculation from the hot engine air blowing out over the genhead and muffler that enters the genhead. Using Prof's idea of the coffee can, this idea has worked. Use the coffee can, leaving the outer end in place and cutting a slit 1 1/2" wide by 4" up one side, turn the can, 110 degrees to the left for air intake. This helped with the problem of hot air recirculation into the genhead. Lining the can with carpet will help lower noise. Air intake for the engine was baffled by using the quietboard.
Testing continues with using a top and no additional fan. This is questionable but with leaving the muffler end open it works. Will get the meter out soon and also test the 3'x 4' rubber one side, carpet the other side DUR-A-BULL mat from Lowe's.
