   My (former) brother-in-law built a special shed for his diesel generator. It was water-cooled, so he set up a the radiator and fan outside the shed. Then he ran the exhaust through a baffled chamber that was at least 20 feet long made out of concrete. That chamber went into a large tube that was routed underground, and exited a ways away from the shed. The shed itself was heavily sound insulated with sound absorbing mats. The whole thing was remarkably quiet. You could not hear the generator until you opened the (sound-insulated) door.

	Since most of the noise is from the exhaust a box is likely to do more harm than good. You could easily overheat the gen and void your warranty. I'd suggest getting an audio db meter and try testing the noise level with and without some temporary panels placed around the generator, far enough away from it not to cause overheat (several feet at least). See if you can make a significant reduction that way. The other thing is to bring a heavy gauge 100 ft extension cord and place the generator out as far as possible with the exhaust pointing away from you and neighboring campsites.

	Anyone here ever build a soundproofing box for a generator?
