With my trusty iPhone app (which I well recognize may be less than precise), the Hondas measure about 80 decibels in Eco mode, warmed up, 30 paces away, with the exhaust pointed away. I agree with my wife; they are louder. Now the app-meter may be off — but off by 30 db? OTOH, this "meter" does allow for calibration. So, next time I will calibrate to the "normal speech" of 60 db at one meter and measure the generators again — though such a calibration may not be accurate throughout the curve. What I would like to do is try a new muffler, but at that price, it's not going to happen.
