1. A method comprising, by a personal audio output device (PAD):
determining, based on a user input in response to an audible output from the PAD, first data representing:
a first threshold sensitivity of a user to a first portion of the audible output in a first frequency band, and
a second threshold sensitivity of the user to a second portion of the audible output in a second frequency band;
determining, using the first data, second data representing a first transfer function for partially compensating for the first threshold sensitivity and the second threshold sensitivity;
computing third data representing first coefficients for a first set of filters having a second transfer function corresponding to the first transfer function;
configuring, using at least the third data, a first equalizer component of the PAD;
generating, using first audio data and the first equalizer component, equalized first audio data; and
outputting first audio corresponding to the equalized first audio data.
