db ratings are not linear. The open frame unit you reference is rated at 64 db which is a LOT louder than one that is say, 56 db which is more in the realm of enclosed RV type inverter units.
Decibels are not linear in terms of power (and energy), but they are pretty near linear with respect to perceived loudness. We don't perceive acoustic power in a linear manner, which is partly why decibels are useful units. An increase of 8 dB is definitely noticeable but not what most people would characterize as a LOT louder.
