Synthesizing a personalized audio equalization filter based on an individual's hearing profile when listening to audio signals using a preferred electronic means of transduction and production of the audio signals through headphones, earphones, or loudspeakers. The deviation of the listener's hearing profile, when the preferred listening device is donned, is measured and recorded relative to predetermined equal-loudness contours (e.g., ISO standard equal-loudness contours). The hearing profile is used to compute an equalization filter such that when the audio signal to be reproduced is played through the filter, the equal-loudness contour for a specified phon level is restored. The equalization filter can be adapted to any phon level through adaptation of filter coefficients as a function of the volume of the listening level. |
