Abstract: to get high sound quality, the proposed adaptive speech compensation (ASC) system fits psychoacoustic curves for individual needs. Moreover, characteristics of the speakers are considered by real-time speaker impedance estimation (RT-SIE) technique. Hence, original signal can be restored for every user with any speakers. ASC system has 99.4% peak original signal recovery rate by predicting and controlling output signal precisely. And the built-in 10Hz high resolution acoustic filter fitting scheme (AFFS) has less than 0.32dB matching error with an over 80dB hearing loss.
