We took the trailer to a state park near Santa Cruz easier this week. Very nice to get away from the heat and smoke.
Unlike most of the places we go, this campground had electrical and water hook-ups. When those are lacking we have a 3800 watt "portable" generator mounted on a rack in front of the trailer. Though, at 100 pounds I don't find it all that portable.
While this generator is pretty quiet to begin with, I built a sound cover to cut the noise even more. It is 1/2 exterior ply coated with epoxy resin and then paint to match the trailer. The inside is lined with rigid acoustical insulation. I was going to add a layer of Mass Load Vinyl, but decided I didn't like the cost or the added weight. That strange looking thing sticking out on the right side is where the exhaust pipe goes and also incorporates a 650 CFM exhaust fan to help keep the gen from overheating in the enclosure. I've determined that my air intake opening on the left side (can't be seen in the pic) is too small for the airflow I think is needed. I will be doing some surgery to remedy that.
At 25 feet I measured 51.5 dB. It isn't the most beautiful thing but does the job.
