i'm sure you can measure a difference with a Sound Db meter
i'm also sure that there is a Tone difference in the sound generated
between Honda and Champion,
I think there are those that think feel that difference and call it a volume difference
for me the Honda and champ side by side, any difference is too small to make it worth a bother
and I know that (2) honda 2000i's running an AC are just as loud as (1) champ 3000i power an identical AC

now if ALL you ever do is charge batteries with a 40a converter
then yes a 2000i honda will be a bit different than a 3000i champ doing the same thing

sound volume is a very personal perception ?

meters don't lie, the difference between champ 2000i and a honda 2000i is only about 1.5 ~ 2 db
it takes 10db for the avg human ear to perceive a doubling of sound
which is really (3) times the sound energy
and there is not that much Measured difference between Honda and champion

I don't know anything about the 10 decibel doubling thing; irrelevant. I do know that 1.5-2 decibels is an audible difference.

Not quite.

Many studies have shown that an increase of 3 db is not a noticeable increase in sound to a human being, it takes an increase of 5 db.

3 db has been the standard threshold to notice a change for decades in the audio industry, seems strange it would vary for a generator. 3 db is also roughly double the sound power level. It takes 10 dbs, 10 times the power, to be perceived as roughly double the loudness by most people. This explains why my old 2200 cheap generator didn't sound all that much louder than my new Honda, in side by side tests with my ear and specs that make it sound like there is a huge difference be damned.
