Looks great John....any sound tests yet?

I did "splurge" for an infrared thermometer - that testing is in progress. The DuroPower was acceptably quiet to begin with, but it is definitely quieter now! I don't have a dB meter, so I'm afraid I can't quantify that for you.
One thing's for sure, when you peck on the metal enclosure panels that are foam lined and now have an inner liner of Hardibacker, you definitely get a satisfying "thud"! Kind of like the difference in shutting the door on a Bentley versus a Volkswagen! HA!
After the season is over, I might works towards enclosing the bottom of the genset - that'll take some well thought-out ducting, but I'm sure then it will be really quiet!
Always a interesting thread. Many EE's/ME's and 'lectricians lurk and post here. To my knowledge, no sound engineer has has come forward. But us of the old schools, will all (I do believe) like the sound trial of 'the Bentley versus VW and the "thud" test:). Personally, I know more about a Volvo S80/T6 than a Bentley. Inside, using the thump test, can't compare as I have no VW, but here is the kicker. My Champion is back in the OEM state. No panels to thump or peck. So, no satisfaction there. I guess all testing of sound (noise) is about vibration and sound waves or lack there of. The open frame on my Champion offers no defence. I think we all are interested in further development of the Chinese DuroPower Genset project. Like the top air flow, carpet lined air duct and the floating cement panels with open bottom? John, thaw soon. The Indians are waiting:W
PS: Love your project. Give us more.
