The problem with quoted dB noise levels is that you must know the conditions under which they were measured. It is really important to know the distance at which the level was measured, since sound drops 6dB for every time the distance is doubled.
Understood. I tried to only look at units with the same posted specs, ie: "74dB at 7 meters" or "65dB at 21 ft." etc. These should be close enough to be consistent. But, there are other factors I am sure that a consumer will never know as far as the area and how the units were measured. All we can go by is what is posted by the manufacturer. Some list at 1/2 load as well as full load, those that don't specify are SUPPOSEDLY at full load. Because I had a specific concern about the noise of my Generac, I made sure that my selection was rated at the same distance and load. The Kipor unit is rated at 64dB at 7 meters and I really can't see how it is so much quieter than the unit I have if both were measured at the same distance and are only 1dB different.
