Many don't know that the sound increases as load increases.
If a gen is running with no load in Economy mode it is the quietest.
If it has 80% or more load it will be at least 10 dB's louder.
So in most cases they probably had different loads.
Yamaha and Honda as well as other similiar inverters are all about the same sound levels.
