AbstractA method and device for compensating for partial hearing loss by converting a time domain signal corresponding to a sound into a series of digital component values in the frequency domain, performing a nonlinear amplitude gain operation in the frequency domain on each of the digital component values and converting the digital component values back into a time domain signal corresponding to the sound with compensation for partial hearing loss.
