Sound Guy 
I suggest you read your Honda Owners Manual or go on line to Honda and find out Honda measures it's dbA's at  9 feet (3 meters) from the control panel side of the generator.
I have, been thru every page, and there is 
no reference whatsoever in my Honda Canada Owner's Manual to sound level measurements for the EU2000i ... nada.  From the 
Honda Canada EU2000i webpage the sound level rating is referenced from 
1.5 to 7 metres.  The 
Honda USA webpage, under SPECS, only refers to load and makes 
no reference to distance.  If you can provide a link to that measurement system you're quoting I'd like to see it.
