1. A method for providing enhanced audio to an individual, tailored to audiological characteristics of the individual, comprising: capturing the individual's audio hearing characteristics, including determining a threshold uncomfortable loudness level of the user for at least one frequency and the individual's minimum audible level for at least one audiometric frequency, at least in part by a self-administered test; analyzing the individual's hearing characteristics to generate an individualized audiological profile; storing the individualized audiological profile in a storage means; using the individualized audiological profile to determine a first frequency-specific gain adjustment for an input audio signal to compensate for frequency-dependent loudness deficits in the individual's hearing; determining a modified audio signal produced by applying the first gain adjustment to an input signal; providing the modified audio signal to the individual using a personal electronic device that reproduces sound; applying a second frequency-specific gain adjustment, input manually by the individual after the modified audio signal is provided to the individual, to convert the modified audio signal to an enhanced audio signal; and providing the enhanced audio signal to the individual using the personal electronic device.
