Generator quieting
I have a Honda 3000 EM, I am looking for some ideas to quiet it down. Anyone had success with this, want to share some ideas?

As far as I can tell, the most cost-effective sound deadening material is called Homasote -- it is sold under a variety of names. Essentially, it comes in half inch thick sheets, 4 feet by 8 feet, and it is compressed cellulose. It sells for about ten or eleven dollars a sheet. You could line the interior of a plastic box with this stuff, and it would not be too heavy, I think. (Obviously, there would have to be an air intake and an exhaust port, with baffles.)
The main problem with Homasote is that it is not weather-proof at all -- a little water and it turns to mush. The other concern is whether it is sufficiently heat resistant for the exhaust baffle -- I would guess it is not.
Maybe there is a cost-effective way to waterproof the cellulose sheeting? And to use something else for the exhaust baffle.
There are commercially available soundproofing materials available for exterior applications, but they are very expensive.
