The answer is No, because there is one more attribute to sound waves that you are familiar with, and that is tone quality. There are individual differences in absolute thresholds. The loudness of sound as perceived by human ears is roughly proportional to the logarithm of sound intensity: when the intensity is very small, the sound is not audible; when it is too great, it becomes painful and dangerous to the ear. The unit of the loudness of sound is decibels which are denoted by dB. Each line of the graph indicates the SPL that is required for the frequencies that are perceived to be equally loud.
