That seems like a much more feasible setup to work with. Especially factoring in less modifications. I'd imagine the shroud it comes in has some noise dampening properties, but you could probably beef those up and maybe add a better muffler to improve things further.
Hmm, what if you were to put a Y pipe in the bus exhaust upstream of the muffler? Being that it's a 4", 5", 6" (???) exhaust, it certainly isn't going to restrict the genny AT ALL. Could it quiet the genny? Hmmm....
And the fact that it weighs about a third of what the other does is pretty critical.
Weight isn't a good thing but I'm sitting at 20,600 lbs with a GVWR at 33,000. I've got a LONG way to go.
Wait, you're right. The first was a 10k unit and that was a 5k unit. Two of them would be lighter than the one. I didn't read thru the specs much. The 10k was 120, 204, and 240 VAC. I don't know if the 5k did all that. Without a dryer, I don't need 204 or 240. Even my MIG is only 120V/20A and it'll run on 120V/15A.
Is the weight difference the 3 phase? If nothing else, the 10k should be "lighter" because it's a single controller, single cabinet, etc. vs. 2 of the 5ks.
I saw a you tube vid. on making generators quieter. Seems like someone used the reflecting angle idea, and it worked pretty good. He may have limited his test to units on concrete, but I remember the sound level was reduced quite a bit.
Haven't seen your video but I'm guessing it depends on how you define quieter. If I have 3 foot thick walls of sound deadening foam and everything is directed out of my window straight at you parked next to me, I won't hear a thing. Sucks to be you but it's quieter in here for me.
Just thinking the directional... if the sound is being redirected (instead of absorbed), it's louder somewhere else but quieter in another.
I don't know the specs but all of the noise specs include a distance from source, at sea level, humidity level, etc. Change those and it will be "quieter".
