Hearing processing method and hearing aid using the same

A hearing aid processing method for a hearing aid processing a sound signal inputted via a microphone so as to output a sound signal from an earphone, comprising the steps of:

• calculating an acoustic nerve excitation pattern of a hearing impaired individual;
• and
• obtaining an output sound signal by multiplying each of frequency components of a power spectrum of an input sound signal by a correction coefficient such that the acoustic nerve excitation pattern of the hearing impaired individual is identical with an acoustic nerve excitation pattern of a normal hearing individual, wherein when the correction coefficient is negative, a phase of the frequency component of the power spectrum is inverted, and the phase-inverted frequency component of the power spectrum is multiplied by an absolute value of the correction coefficient.
