Optimistic Paranoid said:It's interesting that you think that two gennies running in eco mode will be quieter than one gennie running in non-eco mode. I'm not sure that makes sense.
But it's been a few decades since I played around with a sound meter back when I was a rock n roll sound roadie for local bands, so I'm definitely not saying I'm right and you're wrong.
I would be interested in hearing back from you after you try it, or from anyone else here who has actual experience doing this.
I am not 100% sure about the sound/noise either. It's definitely more quiet in Eco mode with one. I saw a video where a guy had four parallel Honda generators in Eco mode running pretty quiet.
The Honda noise range is 57 dB(A) @ rated load 48 dB(A) @ 1/4 load. Two generators running at 48 dB(A) should be more quiet than one at 57 dB(A) I think... I would guess that two running at 48 dB(A) is like one at 51 dB(A). I am not sure what load Eco mode is.
