Champion releases wireless remote start inverter generator

I wonder about how it compared to my 3000 iSE Yamaha. My Yammy is rated at 53-60 dBA, while this is rated at 58 dBa. I'm curious if the Champion model's decibel rating is at no load, no load + econ switch, half load, or full tilt. If the 58 dBs are at full load, that would make it worth having as a backup generator.
