Perceived loudness and physical sound intensity follow different, non-intuitive mathematical scales
Evidence
Intensity, while it has concrete bearing on what sound will do to the hearing apparatus, is not the same metric as perceived loudness, which doubles with every ten-decibel increase, so that going from 40 to 50 decibels equals a rise of 100 percent. — George Michelsen Foy, Zero Decibels, 53
