Perceived loudness doubles with every 10 dB increase, not every 3 dB of intensity.

Evidence

in fact it doesn’t register to my ears as a big change, another indication of how broadly tuned our hearing is. — George Michelsen Foy, Zero Decibels, 97 (#corroborates, via linked claim)

Stevens’ law says that a sensation belonging to the category of intensity sensations grows with physical intensity according to a power law. In consequence of that law, we have to assume that a relative change in loudness is proportional to a relative change in intensity. Specific loudness is developed using this power law. Instead of using the total loudness as the value in question, specific loudness is used. Additionally, instead of intensity, excitation has to be used. — Professor Dr.-Ing.
