This paper investigated the subjective quality of equalized music in which equalization (EQ) curves were tailored to the individuals‚Äô preferences. Listeners subjectively rated a number of pre-selected psychoacoustic-based EQ curves over three test sessions. The personalized EQ curve was the curve that had the highest rating among the pool of pre-selected equalization curves. Listeners were instructed to rate music quality according to the ITU-R BS 1284 scale. Statistical analysis showed that listeners consistently rated music to which personalized EQ curves were applied significantly higher than the original CD-quality music.
