Last year, I made a box for my generator, but I had to leave an open end just to allow air to get in and out, or else it would cut out.
Needless to say, the open ends still allowed a good deal of noise to come through.
I've heard that in Santa Barbara, they're building houses with styrofoam in the walls, and that the insulation from that not only helps with energy reduction, but also noise reduction. You think if I put in a layer of styrofoam that it would help? I would probably still need an open end just for the air-factor, but I could point that towards my truck (if the open end is on top, I still have the lack of oxygen getting in).
Okay, now for a picture of me cooking up some ribs and serving them to my camp neighbors. We formed our own little camp, calling it Camp Chalupacabra. If you want to know the backstory of how that name came about, just ask. The cutie I'm serving ribs to is Brittany from Canada, eh! BTW: This picture was taken by Buddha Scott, one of the Camp Chalupacabrianites.
