that's why generators like the Honda 2000 cost so much. it's more expensive to quiet the engine noise down.
only by building a noise box with fans, can you cut down the noise that comes out of these types of generators.
Well, that's rather disappointing. I really like the larger, open frame generators. When you state "engine noise", what exactly are you referring? The muffler is to dampen/quiet the noise that is created as a direct result of the combustion process. Now, remove any & all combustion noise, and what you have left are actual mechanical noises, ie., valves, springs, pistons, rods, etc., as they do their thing. If that's the noise which you refer, I can't imagine that noise would be so loud as to disturb the general tranquility of the average campground/secluded site....or am I mistaken?
I really think the combustion noise can be reduced a lot more, although it may require a custom fabricated muffler that actually incorporates a larger, heavier-duty style muffler, perhaps originally intended for a small automobile, or similar. It could be done, and shouldn't be that expensive, and any cost would be outweighed by the final result...a super-quiet open frame genny.
I'm not saying you're wrong, just saying that if they already use the quiet mufflers as you said, and I don't doubt you, that with a little creative thinking & mechanical aptitude, a lot more can be done to quiet the beasties down.
