METHOD FOR COMPENSATING A HEARING IMPAIRMENT WITH MULTI-CHANNEL OF DIGITAL A HEARING AID AND A HEARING AID USING THE SAME

摘要

For each channel to fine-tune the frequency characteristics of the hearing loss that occurs differently to nancheongja to use a hearing aid multi-channel digital hearing aids and hearing loss compensation method using the same are disclosed. The present invention includes the steps of converting the external audio signal into a digital signal; A digital signal based on the low frequency band, mid-range, split into a multi-channel step in which a high output in each channel; Separating each digital signs, high-band and low-band part of the signal inputted to each channel; Using the sum of the sine wave generated at a specific separate high-band and low-band part of each sine wave generator to the input signal, based on the input signal using the sine wave by a sum of the specific hearing loss compensation signal by calculating a compensation gain for the band This step, which accumulates the outputs; And after using the hearing loss compensation gain, converts the data into an analog signal a hearing loss compensation, and including the step of outputting the audio signal converted to.
